FACT Descriptions and Family Characteristics
1. Advanced CMOS FACT Logic
FACT logic offers a unique combination of high speed, low power dissipation, high noise immunity, wide
fanout capability, extended power supply range and high reliability.
This data book describes the product line with device specifications as well as material discussing design
considerations and comparing the FACT family to predecessor technologies.
For direct replacement of LS, ALS and other TTL devices, HD74ACT circuits with TTL-type input
thresholds are included in the FACT family. These include the more popular bus drivers/transceivers as
well as many other HD74ACTXXX devices.
1.1 Characteristics

Temperature range –40
°
C to +85
°
C
Improved ESD protection network
High current latch-up immunity
1.2 Interfacing
FACT devices have a wide operating voltage range (V
CC
= 2 to 6 VDC) and sufficient current drive to
interface with most other logic families available today.
Device designators are as follows:
HD74AC is a high-speed CMOS device with CMOS input switching levels and buffered CMOS outputs
that can drive
±
24 mA of I
OH
and I
OL
current. Industry standard HD74AC nomenclature and pinouts are
used.
HD74ACT is a high-speed CMOS device with a TTL-to-CMOS input buffer stage. These device inputs
are designed to interface with TTL outputs operating with a V
CC
= 5 V
±
0.5 V with V
OH
= 2.4 V and V
OL
= 0.4 V, but are functional over the entire FACT operating voltage range of 2.0 to 5.5 VDC. These
devices have buffered outputs that will drive CMOS or TTL devices with no additional interface
circuitry. HD74ACT devices have the same output structures as HD74AC devices.
