Description
The 74VHC373F is an advanced high-speed CMOS octal D-type latch with 3-STATE output fabricated with silicon gate CMOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining low power dissipation. This 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE). The latches appear transparent to data when the latch enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. When the OE input is HIGH, the eight outputs are in a high impedance state.
An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup.This circuit prevents device destruction due to mismatched supply and input voltages.
Specifications and Features
- High Speed: tPD = 5.0ns (typ) @ VCC = 5V
- High Noise Immunity: VNIH = VNIL = 28% VCC (Min.)
- Power Down Protection is provided on all inputs
- Low Noise: VOLP = 0.6V (Typ.)
- Low Power Dissipation: ICC = 4µA (Max) @ TA = 25°C
- Pin and Function Compatible with 74HC373
Application Scenarios
The 74VHC373F can be used in various electronic systems that require high-speed data latching and low power dissipation. It is especially suitable for systems that interface 5V to 3V and two supply systems such as battery backup.
