Major Logic Chip Families

This is not an exhaustive list, but the lists the families that had the greatest impact on the industry. I have not listed second source versions of the families. Second sourcing was very common with most of the major companies second sourcing each other.

CTR- Commercial Temperature Range is 0⁰ to 70⁰C

MTR - Military Temperature Range is -55⁰ to +125⁰C

Bipolar  ----------------------------------------

RCTL - Resistor-Capacitor-Transistor Logic

A relative of RTL logic. A RCTL gate performs at higher speeds through the use of a capacitor.

 

1960's

- Texas Instruments 51 and 51R (R's high stress tested 51's) Series - (Announced in March 1960, Electronics News)

 

DCTL - Direct Coupled Transistor Logic

A special type of RTL logic. A DCTL gate is one wherein the bases of the transistors are connected directly to inputs without any base resistors. Without the base resistors, DCTL gates are more economical and simpler to fabricate onto integrated circuits than RTL gates with base resistors.

 

- Fairchild MicroLogic 900 series - Fairchild's first logic chips (Announced in November 1960, Electronics News)

 

RTL - Resistor-Transistor Logic

One of the earliest families, RTL had several drawbacks, such as bulkiness, low speed, limited fan-out, and poor noise margin.

 

1960's - 

 

- Texas Instruments 17900L Series

- Texas Instruments 17800L Series

- Motorola MC700G Series (+15⁰ to +55⁰C) - includes milliwatt and medium power devices

- Motorola MC800G/MC900G Series (800 is +0⁰ to +100⁰C/900 is MTR) 

- Motorola MC708, 808, 908 Series (MTR) - milliwatt power devices

 

DTL - Diode-Transistor Logic

One of the early circuit types to be integrated. Slower than RTL's, but handled noise better. It had a greater fanout range.

 

1960's

- Signetics SE100 series (1962)

- Fairchild MicroLogic 930 series

- Texas Instruments 53/73 Series - Modified-DTL's (military versions)

- Texas Instruments 15 Series

- National Semiconductor 930 Series

- Motorola MC200/250 Series (MTR/CTR)

- Motorola MC830/930 Series (CTR/MTR) - MDTL's (Monolithic integrated DTL's)

ECL - Emitter-Coupled Logic

Very high speed devices. Selected over TTL for very fast applications. 

 

1960's

- Texas Instruments 2500 Series

- Motorola MECL MC300/350 Series (MTR/CTR) (1962)

- Motorola MECL 10,000 Series

- Motorola MECL 100,000 Series

TTL - Transistor-Transistor Logic

1960's

- Texas Instruments 54/74 Series - Standard TTL's (54 = MTR/ 74 = CTR) (1964)

- Texas Instruments SNG/SNF 54/74 Series

- Texas Instruments 54H/74H Series - High Voltage/High Speed TTL's (Motorola 3000/3100 series)

- Texas Instruments 54L/74L Series - Low Power/Low Speed TTL's 

- Fairchild 9000 Series - SSI Circuits

- Fairchild 9300 Series - MSI Circuits

 

1970's

- Texas Instruments 54S/74S - High Speed

- Texas Instruments 54LS/74LS - Low Power, 54/74 Speeds

- Texas Instruments 29000 - Direct replacement for Fairchild series 9000 TTL's

- Texas Instruments 29300/39300 - Direct replacement for Fairchild series 9300 TTL's (29 = MTR, 39 = CTR)

 

- 54ALS/74ALS

 

1980's

- Signetics 74F - Very Fast TTL (NPN based, pin compatible with 74S)

 

CTL -

Economical high speed device. Good power dissipation, but required additional design considered because logic levels were non-restoring. 

HTL - High Voltage-Transistor Logic

DC UTL - Direct Couple Unipolar Transistor Logic

HTTL

LTTL

Variable-Threshold Logic
