Inverting, 3-State Outputs

TC74HC541AP/AF

Non-Inverting,

3-State Outputs

The TC74HC540A/TC74HC541A are high speed CMOS OCTAL

BUS BUFFERs fabricated with silicon gate C2MOS technology.

They achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The TC74HC540A is an inverting type, and the TC74HC541A

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 = 10 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)

• Output Drive Capability: 15 LSTTL loads

• Symmetrical output impedance: |IOH| = IOL = 6 mA (min)

• Balanced propagation delays: tpLH ∼− tpHL

• Wide operating voltage range: VCC (opr) = 2 to 6 V

• Pin and function compatible with 74LS540/541
