MC74VHC573
Octal D-Type Latch with
3-State Output
The MC74VHC573 is an advanced high speed CMOS octal latch
with 3âstate output fabricated with silicon gate CMOS technology. It
achieves high speed operation similar to equivalent Bipolar Schottky
TTL while maintaining CMOS low power dissipation.
This 8âbit Dâtype latch is controlled by a latch enable input and an
output enable input. When the output enable input is high, the eight
outputs are in a high impedance state.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems
to 3 V systems.
⢠High Speed: tPD = 4.5 ns (Typ) at VCC = 5 V
⢠Low Power Dissipation: ICC = 4 μA (Max) at TA = 25°C
⢠High Noise Immunity: VNIH = VNIL = 28% VCC
⢠Power Down Protection Provided on Inputs
⢠Balanced Propagation Delays
⢠Designed for 2 V to 5.5 V Operating Range
⢠Low Noise: VOLP = 1.2 V (Max)
⢠Pin and Function Compatible with Other Standard Logic Families
⢠Latchup Performance Exceeds 300 mA
⢠ESD Performance: HBM > 2000 V; Machine Model > 200 V
⢠Chip Complexity: 218 FETs or 54.5 Equivalent Gates
⢠These Devices are PbâFree and are RoHS Compliant
