SN54HC273, SN74HC273 SCLS136F - DECEMBER 1982 - REVISED APRIL 2022 SNx4HC273 Octal D-Type Flip-Flops With Clear 1 Features - Wide operating voltage range of 2 V to 6 V - Outputs can drive up to 10 LSTTL loads - Low power consumption, 80-µA maximum ICC - Typical tpd = 12 ns - ±4-m A output drive at 5 V - Low input current of 1-µA maximum - Contain eight flip-flops with single-rail outputs - Direct clear input - Individual data input to each flip-flop - On products pliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. On all other products, production processing does not necessarily include testing of all parameters. 2 Applications - Buffer or storage registers - Shift registers - Pattern generators 3 Description The SNx4HC273 devices are positive-edge-triggered D-type flip-flops with a direct active low clear ( CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
