Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

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. ■ 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 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.

When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D input changes. When LE is LOW, the latches store the information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-STATE standard outputs are controlled by the Output Enable (OE) input. When OE is LOW, the standard outputs are in the 2-state mode. When OE is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.
