Overview
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 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 a...
