General Description

The LVTH125 contains four independent non-inverting buffers with 3-STATE outputs.

These buffers are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVTH125 is fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.

Features

■ Input and output interface capability to systems at 5V VCC

■ Bushold data inputs eliminate the need for external

pull-up resistors to hold unused inputs

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free bus loading

■ Outputs source/sink –32mA/+64mA

■ Functionally compatible with the 74 series 125

■ Latch-up performance exceeds 500mA

■ ESD performance:

– Human-body model > 2000V

– Machine model > 200V

– Charged-device model > 1000V
