Octal Bus Buffer

TC74VHCT540AF/AFT/AFK

Inverted, 3-State Outputs

TC74VHCT541AF/AFT/AFK

Non-Inverted, 3-State Outputs

The TC74VHCT540A and 541A 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 TC74VHCT540A is an inverting type and, the

TC74VHCT541A is a non-inverting type.

When either

1

G

or

2

G

are high, the terminal outputs are in

the high-impedance state.

The input voltage are compatible with TTL output voltage.

These devices may be used as a level converter for interfacing

3.3 V to 5 V system.

Input protection and output circuit ensure that 0 to 5.5 V can

be applied to the input and output (Note) pins without regard to

the supply voltage. These structure prevents device destruction

due to mismatched supply and input/output voltages such as

battery back up, hot board insertion, etc.

Note:

Output in off-state

Features

• High speed: tpd = 5.4 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)

• Power down protection is provided on all inputs and outputs

• Balanced propagation delays: tpLH ∼− tpHL

• Low noise: VOLP = 1.6 V (max)

• Pin and function compatible with the 74 series

(74AC/HC/F/ALS/LS etc.) 540/541 type.
