HD74HC373 Datasheet Octal D-type Transparent Latches

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC373, HD74HC533 Octal D-type Transparent Latches (with 3-state outputs) Octal D-type Transparent Latches (with inverted 3-state outputs) REJ03D0619-0200 (Previous ADE-205-498) Rev.2.

General 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.

Key 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) Package Abbreviation HD74HC373P HD74HC533P DILP-20 pin PRDP0020AC-B (DP-20NEV) P HD74HC373FPEL HD74HC533FPEL SOP-20.
