CD54HC4020, CD74HC4020, CD54HCT4020, CD74HCT4020 SCHS201D - FEBRUARY 1998 - REVISED AUGUST 2022 CDx4HC4020, CDx4HCT4020 CDHigh-Speed CMOS Logic 14-Stage Binary Counter 1 Features - Fully static operation - Buffered inputs - mon reset - Negative edge clocking - Fanout (over temperature range) - Standard outputs: 10 LSTTL loads - Bus driver outputs: 15 LSTTL loads - Wide operating temperature range: -55℃ to 125℃ - Balanced propagation delay and transition times - Significant power reduction pared 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 patibility, VIL = 0.8 V (max), VIH = 2 V (min) - CMOS input patibility, II ≤ 1 µA at VOL,VOH 2 Description The ’HC4020 and ’HCT4020 are 14-stage ripple-carry binary counters. All counter stages are controller/ peripheral flip- flops. The state of the stage advances one count on the negative clock transition of each input pulse; a high voltage level on the MR line resets all counters to their zero state. All inputs and outputs are buffered. PART NUMBER Device Information PACKAGE(1) BODY SIZE...
