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
