SN74HC273 (ACTIVE)

Octal D-Type Flip-Flops With Clear

Octal D-Type Flip-Flops With Clear - SN74HC273
 

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.

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.
