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-mA 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 compliant 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

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.
