Non-Inverting, 3-State

Outputs

The TC74AC540/TC74AC541 are advanced high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate and

double-layer metal wiring C2MOS technology.

They achieve the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

The TC74AC540 is an inverting type, and the TC74AC541 is a

non-inverting type.

When either

1

G

or

2

G

are high, the terminal outputs are in

the high-impedance state.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• High speed: tpd = 4.0 ns (typ.) at VCC = 5 V

• Low power dissipation: ICC = 8 μA (max) at Ta = 25°C

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

• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)

Capability of driving 50

Ω

transmission lines.

• Balanced propagation delays: tpLH ∼− tpHL

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

• Pin and function compatible with 74F540/541
