1 Features
• Buffered inputs
• Asynchronous reset
• Typical fMAX = 60 MHz at VCC = 5 V, CL = 15 pF, TA = 25 °C
• Fanout (over temperature range)
– Standard Outputs : 10 LSTTL loads
– Bus driver outputs : 15 LSTTL loads
• Wide operating temp range : – 55 °C to 125 °C
• Balanced propagation delay and transition times
• Significant power reduction compared to LSTTL logic ICs
• HC types
– 2 V to 6 V operation
– High noise immunity : NIL = 30%, NIH = 30% of VCC at VCC = 5 V
• HCT types
– 4.5 V to 5.5 V operation
– Direct LSTTL input logic compatibility, VIL = 0.8 V (Max), VIH = 2 V (Min)
– CMOS input compatibility, II ≤ 1 μA at VOL, VOH
2 Description
The ’HC164 and ’HCT164 are 8-bit serial-in parallelout shift registers with asynchronous reset. Data is shifted on the positive edge of Clock (CLK). A LOW on the Reset (CLR) pin resets the shift register and all outputs go to the LOW state regardless of the input conditions. Two Serial Data inputs (A and B) are provided, either one can be used as a Data Enable control.
