3 Description

The SN74HCT595-Q1 device contains an 8-bit, serialin,

parallel-out shift register that feeds an 8-bit D-type

storage register. The storage register has parallel

3-state outputs. Separate clocks are provided for

both the shift and storage register. The shift register

has a direct overriding clear (SRCLR) input, serial

(SER) input, and a serial output (QH') for cascading.

When the output-enable (OE) input is high, the

storage register outputs are in a high-impedance

state. Internal register data and serial output (QH') are

not impacted by the operation of the OE input.
