HD74HC166 Datasheet Parallel-load 8-bit Shift Register

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC166 Parallel-load 8-bit Shift Register.

General Description

This device is an 8-bit shift register with an output from the last stage.

Data may be loaded into the register either in parallel or in serial form.

When the Shift/Load input is low, the data is loaded asynchronously in parallel.

Key Features

  • High Speed Operation: tpd (Clock to QH) = 14 ns typ (CL = 50 pF) High Output Current: Fanout of 10 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) Function Table Inputs Parallel Clear L H H H H H Shift/Load X X L H H X Clock Inhibit X L L L L H Clock X L Serial X X X H L X A.
  • H X X a.
  • h X X X Internal Outputs QA L QA0 a.
