The MM74HC165 high speed parallel-in/serial-out shift register utilizes advanced silicon-gate CMOS technology. It has the low power consumption and high noise immunity of standard CMOS integrated circuits, along with the ability to drive 10 LS-TTL loads.  This 8-bit serial shift register shifts data from QA to QH when clocked. Parallel inputs to each stage are enabled by a low level at the shift/load input. Also included is a gated clock input and a complementary output from the eighth bit.

 Features:

• Typical propagation delay: 20 ns (clock to Q)
• Wide operating supply voltage range: 2–6V
• Low input current: 1 A maximum
• Fanout of 10 LS-TTL loads
• Low quiescent supply current: 80 A maximum (74HC Series)

Key Specifications:

• Power requirements: 2 to 6 VDC
• Communication: parallel-in/serial-out
• Dimensions: 0.74 x 0.25 x 0.145 in (18.8 x 6.4 x 3.7mm)
• Operating temp range: -40 to +158 °F (-40 to +85 °C)
