74LCX16240

Low voltage CMOS 16-bit bus buffer (3-state)

with 5V tolerant inputs and outputs

Features

■ 5V tolerant inputs and outputs

■ High speed:

– t = 4.5ns (Max) at V = 3V

■ Power down protection on inputs and outputs

■ Symmetrical output impedance:

TSSOP48

– |I | = I = 24mA (Min) at V = 3V

■ PCI bus levels guaranteed at 24mA

■ Balanced propagation delays:

The 74LCX16240 is a low voltage CMOS 16 BIT

BUS BUFFER fabricated with sub-micron silicon

gate and double-layer metal wiring C MOS

■ Operating voltage range:

– V (Opr) = 2.0V to 3.6V

technology. It is ideal for low power and high

speed 3.3V applications; it can be interfaced to

5V signal environment for both inputs and

outputs.

■ Pin and function compatible with

74 series 16240

■ Latch-up performance exceeds

500mA (JESD 17)

Any nG output control governs four BUS

BUFFERS. Output Enable input (nG) tied together

gives full 16-bit operation.

■ ESD performance:

– HBM > 2000V

(MIL STD 883 method 3015); MM > 200V

When nG is LOW, the outputs are on. When nG is

HIGH, the output are in high impedance state.

This device is designed to be used with 3 state

memory address drivers, etc.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
