HD74HC373 - Octal D-type Transparent Latches

Datasheet Summary

Description

When the latch enable input is high, the Q outputs of HD74HC373 will follow the D inputs and the Q outputs of HD74HC533 will follow the inversion of the D inputs.

When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again.

Features

  • High Speed Operation: tpd (D to Q) = 16 ns typ (CL = 50 pF).
  • High Output Current: Fanout of 15 LSTTL Loads.
  • Wide Operating Voltage: VCC = 2 to 6 V.
  • Low Input Current: 1 µA max.
  • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C).
  • Ordering Information Part Name Package Type Package Code (Previous Code) HD74HC373P HD74HC533P DILP-20 pin PRDP0020AC-B (DP-20NEV) HD74HC373FPEL HD74HC533FPEL SOP-20 pin (JEITA) PRSP0020DD-.

HD74HC373, HD74HC533 Octal D-type Transparent Latches (with 3-state outputs) Octal D-type Transparent Latches (with inverted 3-state outputs) REJ03D0619-0300 Rev.3.00 Mar 25, 2009 Description When the latch enable input is high, the Q outputs of HD74HC373 will follow the D inputs and the Q outputs of HD74HC533 will follow the inversion of the D inputs. When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
