74F166 Datasheet (NXP) - 8-bit bidirectional universal shift register

74F166, 8-bit bidirectional universal shift register

The 74F166 is a high speed 8 *bit shift register that has fully synchronous serial parallel data entry selected by an active low parallel enable (PE) input.

When the PE is low one setup time before the low *to *high clock transition, parallel data is entered into the register.

74F166 Features

* High impedance NPN base inputs for reduced loading

* (20µA in high and low states) Synchronous parallel to serial applications Synchronous serial data input for easy expansion Clock enable for ”do nothing” mode Asynchronous master
