1. General description

The 74HC4094-Q100; 74HCT4094-Q100 is an 8-bit serial-in/serial or parallel-out shift register with

a storage register and 3-state outputs. Both the shift and storage register have separate clocks.

The device features a serial input (D) and two serial outputs (QS1 and QS2) to enable cascading.

Data is shifted on the LOW-to-HIGH transitions of the CP input. Data is available at QS1 on the

LOW-to-HIGH transitions of the CP input to allow cascading when clock edges are fast. The same

data is available at QS2 on the next HIGH-to-LOW transition of the CP input to allow cascading

when clock edges are slow. The data in the shift register is transferred to the storage register

when the STR input is HIGH. Data in the storage register appears at the outputs whenever the

output enable input (OE) is HIGH. A LOW on OE causes the outputs to assume a high-impedance

OFF-state. Operation of the OE input does not affect the state of the registers. Inputs include clamp

diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of

VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
