TECHNICAL DATA
Octal D-type transparent latch; 3-state
The IN74LV373 is a low-
voltage Si-gate
CMOS devise and is pin and function compatible with 74HCT373. The IN74LV373 is an octal D-type transparent latch featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. A latch enable (LE) input and an output enable (OE) input are common to all intemal latches. Outputs Directly Interface to
CMOS, NMOS, and TTL Operating
Voltage Range: 1.2 to 3.6 V Low Input Current: 1.0 µA High Noise Immunity Characteristic of
CMOS Devices
