CD54HC164, CD74HC164, CD54HCT164, CD74HCT164 SCHS155E - NOVEMBER 1998 - REVISED MAY 2024 CDx4HC164, CDx4HCT164 High-Speed CMOS Logic 8-Bit Serial-In, Parallel-Out Shift Register 1 Features - Buffered inputs - Asynchronous reset - Typical f MAX = 60MHz at VCC = 5V, CL = 15p F, TA = 25°C - Fanout (overtemperature 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 pared to LSTTL logic ICs - HC types - 2V to 6V operation - High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V - HCT types - 4.5V to 5.5V operation - Direct LSTTL input logic patibility, VIL = 0.8V (Max), VIH = 2V (Min) - CMOS input patibility, II ≤ 1μA 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. PART NUMBER CD74HC164M CD74HCT164M CD74HC164E CD74HCT164E CD54HC164F Device...
