Octal D-Type Flip-Flop with Clear

The TC74VHC273 is an advanced high speed CMOS OCTAL

D-TYPE FLIP FLOP fabricated with silicon gate C2MOS

technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

Information signals applied to D inputs are transferred to the

Q outputs on the positive going edge of the clock pulse.

When the CLR input is held “L”, the Q outputs are at a low

logic level independent of the other inputs.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• High speed: fmax = 165 MHz (typ.) at VCC = 5 V

• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C

• High noise immunity: VNIH = VNIL = 28% VCC (min)

• Power down protection is provided on all inputs.

• Balanced propagation delays: tpLH ∼− tpHL

• Wide operating voltage range: VCC (opr) = 2 to 5.5 V

• Low noise: VOLP = 0.8 V (max)

• Pin and function compatible with 74ALS273
