Product Summary

The NTE74HC273 is a high-speed octal D−type flip−flop with a direct clear input in a 20−Lead DIP-type package manufactured with silicon−gate CMOS technology that has the low-power consumption of standard CMOS integrated circuits. Information at the D inputs is transferred to the Q outputs on the positive−going edge of the clock pulse. All eight flip−flops are controlled by common clock (CP) and a common reset (MR). Resetting is accomplished by a low voltage level independent of the clock. All eight Q outputs are reset to a logic 0.

  • Wide power supply range: 2V to 6V
  • High-noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
  • Common clock and asynchronous master reset
  • Positive-edge triggering
  • Buffered inputs
  • Fanout (over temp rng):
    Std. outputs: 10 LS−TTL loads
    Bus driver outputs: 15 LS−TTL loads
  • Balanced propagation delay and transition times
  • Significant power reduction compared to LS−TTL logic ICs
  • Absolute maximum ratings:*
    VCC: −0.5 to +7.0V
  • IIK, IOK: &plusnm;20mA
  • DC drain current (per output), IOUT: &plusnm;25mA
  • DC output source or sink current (per output), IOUT: &plusnm;25mA
  • DC VCC or GND current (per pin), ICC: &plusnm;50mA
  • TJ: +150°C
  • Tstg: −65°C to +150°C
  • RthJA: 69°C/W
  • TL: +300°C
