TC74HCT541AP/AF

Non-Inverting,

3-State Outputs

The TC74HCT540A/TC74HCT541A are high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate C2MOS

technology.

These devices may be used as a level converter for interfacing

TTL or NMOS to High Speed CMOS. The inputs are compatible

with TTL, NMOS and CMOS output voltage levels.

They achive the high speed operation similar to equivalent

LSTTL while maintaing the CMOS low power dissipation.

The TC74HCT540A is an inverting type, and the

TC74HCT541A 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

• Compatible with TTL outputs: VIL = 0.8 V (max)

VIH = 2.0 V (min)

• Wide interfacing ability: LSTTL, NMOS, CMOS

• Output drive capability: 15 LSTTL loads

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

• Balanced propagation delays: tpLH ∼− tpHL

• Pin and function compatible with 74LS540/541
