Datasheet

ºìÌÒÊÓƵ

Overview

The VHC373 is an advanced high speed CMOS octal D-type latch with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS 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 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 back up. This circuit prevents device destruction due to mismatched supply and input voltages.

  • This product is general usage and suitable for many different applications.

  • High Speed: tPD = 5.0 ns (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 = 4 µA (Max) @ TA = 25°C
  • Pin and Function Compatible with 74HC373

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
