Product data sheet
1. General description
The 74HC164; 74HCT164 is an 8-bit serial-in/parallel-out shift register. The device
features two serial data inputs (DSA and DSB), eight parallel data outputs (Q0 to Q7).
Data is entered serially through DSA or DSB and either input can be used as an active
HIGH enable for data entry through the other input. Data is shifted on the LOW-to-HIGH
transitions of the clock (CP) input. A LOW on the master reset input (MR) clears the
register and forces all outputs LOW, independently of other inputs. Inputs include clamp
diodes. This enables the use of current limiting resistors to interface inputs to voltages in
excess of VCC.
