The TC74VHC240 and 244 are advanced high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate C2MOS

technology.

They achieve the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

The 74VHC240 is an inverting 3-state buffer having two

active-low output enables. The TC74VHC244 is a non-inverting

3-state buffer, and has two active-low output enables.

These devices are designed to be used with 3-state memory

address drivers, etc.

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: tpd = 3.9 ns (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 74ALS240/244
