7400 시리즈 집적 회로 목록 - List of 7400-series integrated circuits

다음은 7400 시리즈 디지털 논리 집적 회로 의 목록입니다 . 1960 년대 중반 텍사스 인스트루먼트 는 원래 7400 시리즈 집적 회로 를 접두사 "SN"과 함께 도입하여 SN74xx라는 이름을 만들었습니다. 이러한 부품의 인기로 인해 다른 제조업체는 핀 대 핀 호환 논리 장치를 출시하고 호환 부품을 식별하는 데 도움이되도록 7400 시퀀스 번호를 유지했습니다. 그러나 다른 제조업체는 부품 번호에 다른 접두사와 접미사를 사용합니다.

개요

일부 TTL 로직 부품은 확장 된 군사 사양 온도 범위로 제작되었습니다. 이러한 부품은 부품 번호에서 74 대신 54 로 시작됩니다 . [1]

Texas Instruments 부품의 수명이 짧은 64 접두사는 산업 온도 범위를 나타냅니다. 이 접두사는 1973 년 TI 문헌에서 삭제되었습니다. 대부분의 최신 7400 시리즈 부품은 TTL이 아닌 CMOS 또는 BiCMOS 기술 로 제작됩니다 . 단일 게이트가있는 표면 실장 부품 (종종 5 핀 또는 6 핀 패키지)에는 74 대신 741G 접두사가 붙습니다 .

일부 제조업체는 접두사가 74 인 4000 시리즈 등가 CMOS 회로를 일부 출시 했습니다. 예를 들어 74HC4066 [2] 는 전기적 특성이 약간 다른 4066을 대체했습니다 (다양한 전원 공급 장치 정격 전압, 더 높은 주파수 기능, 낮은 "on"저항). 아날로그 스위치 등). 4000 시리즈 집적 회로 목록을 참조하십시오 . 반대로 4000 시리즈는 7400 시리즈에서 "차용"했습니다. 예를 들어 CD40193 및 CD40161은 74C193 및 74C161의 핀 대 핀 기능 대체품입니다.

Signetics , Motorola , Mullard 및 Siemens 와 같은 제조업체에서 만든 이전 TTL 부품은 유럽 ​​FJ 제품군에서와 같이 완전히 다른 숫자 접두사와 번호 매기기 시리즈를 가질 수 있습니다 .FJH101은 7430과 같은 8 입력 NAND 게이트 입니다.

특정 논리 하위 제품군 을 지정하기위한 몇 개의 알파벳 문자 는 부품 번호에서 74 또는 54 바로 뒤에 올 수 있습니다 (예 : 저전력 쇼트 키의 경우 74LS74) . TTL 호환 입력 임계 값이있는 고속 CMOS 용 74HCT74와 같은 일부 CMOS 부품 은 기능적으로 TTL 부품과 유사합니다. 모든 제품군에서 모든 기능을 사용할 수있는 것은 아닙니다. 이러한 알파벳 문자의 일반적인 설명 기능은 절정에 시장에 참여한 여러 회사에 의해 희석되었으며 특히 최신 제품과 항상 일치하지는 않습니다. FAST [3] 및 FACT [4] 라는 단어의 National Semiconductor 상표일반적으로 다른 회사의 고유 한 명칭을 설명 할 때 설명에 인용됩니다. [5] [6]

7478 및 74107과 같은 몇몇 경우에 다른 제품군의 동일한 접미사는 완전히 동일한 논리 기능을 갖지 않습니다.

이 시리즈의 또 다른 확장은 7416xxx 변형으로, 끝자리 가 같은 8 비트 "기본"칩의 대부분 16 비트 폭을 나타냅니다. 따라서 예를 들어 "7416373"은 "74373"에 해당하는 16 비트 폭입니다. 그러나 일부 7416xxx 부품은 표준 74xxx 범위와 직접적으로 대응하지 않지만 대신 새로운 기능을 제공하므로 7416xxx 시리즈의 더 높은 핀 수를 사용해야합니다. 자세한 내용은 주로 참조 섹션에 언급 된 Texas Instruments 설명서를 참조하십시오.

CMOS (AC, HC 등) 하위 제품군의 경우 아래 표에서 " 오픈 컬렉터 "에 대한 " 오픈 드레인"을 읽으 십시오.

74453과 같이 충돌하는 할당이 여러 개있는 숫자 접미사가 몇 개 있습니다.

더 큰 발자국

이 섹션의 부품은 핀 수가 14 개 이상입니다. 1960 년대와 1970 년대에 더 낮은 부품 번호가 설정되었으며 이후 수십 년에 걸쳐 더 높은 부품 번호가 점진적으로 추가되었습니다. IC 제조업체는 계속해서이 그룹의 핵심 하위 집합을 만들고 있지만 이러한 부품 번호 중 상당수는 구식으로 간주되어 더 이상 제조되지 않습니다. 일부는 찾기가 훨씬 어렵지만 오래된 단종 된 부품은 제한된 수의 판매자로부터 새로운 오래된 재고 (NOS) 로 구입할 수 있습니다 .

다음 표의 경우 :

  • 부품 번호 열- "x"는 논리 하위 제품군 이름 의 자리 표시 자입니다 . 예를 들어, "LS"로직 제품군의 74x00은 "74LS00"이됩니다.
  • 설명 열-Schmitt trigger, open-collector / open-drain, three-state라는 용어가 입력 및 출력 열로 이동되어 이러한 기능을 기준으로 쉽게 정렬 할 수 있습니다.
  • 입력 열-빈 셀은 논리 제품군 유형에 대한 일반 입력을 의미합니다.
  • 출력 열-빈 셀은 푸시 풀 출력 이라고도하는 '토템폴'출력을 의미하며 동일한 논리 하위 제품군의 표준 입력 10 개를 구동 할 수 있습니다 ( 팬 아웃 N O = 10). 출력 전류가 더 높은 출력을 종종 드라이버 또는 버퍼라고합니다.
  • 핀 열- 듀얼 인라인 패키지 버전 의 핀 수 . 괄호 안의 숫자는이 IC의 알려진 이중 인라인 패키지 버전이 없음을 나타냅니다.

Smaller footprints

As board designs have migrated away from large amounts of logic chips, so has the need for many of the same gate in one package. Since about 1996,[7] there has been an ongoing trend towards one / two / three logic gates per chip. Now logic can be placed where it is physically needed on a board, instead of running long signal traces to a full-size logic chip that has many of the same gate.[8]

All chips in the following sections are available 5 to 10 pin surface mount packages. The right digits, after the 1G/2G/3G, typically has the same functional features as older legacy chips, except for the multifunctional chips and 4-digit chip numbers which are unique to these newer families. The "x" in the part number is a place holder for the logic family name. For example, 74x1G14 in "LVC" logic family would be "74LVC1G14". The previously stated prefixes of "SN-" and "MC-" are used to denote manufacturers, Texas Instruments and ON Semiconductor respectively.[9][10][11]

Some of the manufacturers that make these smaller IC chips are: Diodes Incorporated, Nexperia (NXP Semiconductors), ON Semiconductor (Fairchild Semiconductor), Texas Instruments (National Semiconductor), Toshiba.

The logic families available in small footprints are: AHC, AHCT, AUC, AUP, AXP, HC, HCT, LVC, VHC, NC7S, NC7ST, NC7SU, NC7SV. The LVC family is very popular in small footprints because it supports the most common logic voltages of 1.8V, 3.3V, 5V, its inputs are 5V tolerant when the device is powered at a lower voltage, and an output drive of 24 mA. Gates that are commonly available across most small footprint families are 00, 02, 04, 08, 14, 32, 86, 125, 126.
