MC74VHC573
Octal D−Type Latch with
3−State Output
The MC74VHC573 is an advanced high speed CMOS octal latch
with 3−state 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 8−bit D−type 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 7V, allowing the interface of 5V systems
to 3V systems.
• High Speed: t_PD = 4.5ns (Typ) at V_CC = 5V
• Low Power Dissipation: I_CC = 4μA (Max) at T_A = 25°C
• High Noise Immunity: V_NIH = V_NIL = 28% V_CC
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Designed for 2V to 5.5V Operating Range
• Low Noise: V_OLP = 1.2V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V
• Chip Complexity: 218 FETs or 54.5 Equivalent Gates
