CD54HC273, CD74HC273 CD54HCT273, CD74HCT273 SCHS174C - FEBRUARY 1998 - REVISED JANUARY 2022 CDx4HC(T)273 High-Speed CMOS Logic Octal D-Type Flip-Flop with Reset 1 Features - mon clock and asynchronous controller reset - Positive edge triggering - Buffered inputs - 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 = 5V - 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 ’HC273 and ’HCT273 high speed octal D-Type flip-flops with a direct clear input are manufactured with silicon-gate CMOS technology. They possess the low power consumption of standard CMOS integrated circuits. Information at the D input is transferred to the Q outputs on the positive-going edge of the clock pulse. All eight flip-flops are controlled by a mon clock (CLK) and a mon reset (CLR). Resetting is acplished by a low voltage level independent of the clock. All eight Q outputs are reset to a logic 0.
