74LVT245, 74LVTH245 Low Voltage Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs
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 (74LVTH245), also available without bushold feature (74LVT245)
■ Live insertion/extraction permitted ■ Power Up/Down high impedance provides glitch-free
bus loading ■ Outputs source/sink, –32mA/+64mA ■ Latch-up performance exceeds 500mA ■ ESD performance:
– Human-body model > 2000V – Machine model > 200V – Charged-device model > 1000V
General Description
The LVT245 and LVTH245 contain eight non-inverting bidirectional buffers with 3-STATE outputs and are intended for bus-oriented applications. The Transmit/ Receive (T/R) input determines the direction of data flow through the bidirectional transceiver.
