General Description

The LVT245 and LVTH245 contain eight non-inverting bidirectionalbuffers with 3-STATE outputs and are intended forbus-oriented applications. The Transmit/Receive (T/R)input determines the direction of data flow through the bidirectionaltransceiver.

Transmit (active-HIGH) enables datafrom A ports to B ports; Receive (active-LOW) enablesdata from B ports to A ports. The Output Enable input,when HIGH, disables both A and B ports by placing them ina HIGH Z condition.

The LVTH245 data inputs include bushold, eliminating theneed for external pull-up resistors to hold unused inputs.These transceivers are designed for low-voltage (3.3V)VCC applications, but with the capability to provide a TTLinterface to a 5V environment.

The LVT245 and LVTH245are fabricated with an advanced BiCMOS technology toachieve high speed operation similar to 5V ABT whilemaintaining a low power dissipation.


Features

■ Input and output interface capability to systems at5V VCC

■ Bushold data inputs eliminate the need for externalpull-up resistors to hold unused inputs (74LVTH245),also available without bushold feature (74LVT245)

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-freebus loading

■ Outputs source/sink, 32 mA/64 mA

■ Latch-up performance exceeds 500 mA

■ ESD performance:Human-body model ! 2000VMachine model ! 200VCharged-device model ! 1000V
