74LVT245 • 74LVTH245 Low Voltage Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs November 1999 Revised November 2000 74LVT245 74LVTH245 Low Voltage Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs General Description Features The LVT245 and LVTH245 contain eight non-inverting bidi-Input and output interface capability to systems at rectional buffers with 3-STATE outputs and are intended for 5V V CC bus-oriented applications. The Transmit/Receive (T/R) Bushold data inputs eliminate the need for external input determines the direction of data flow through the bidi- pull-up resistors to hold unused inputs (74LVTH245), rectional transceiver. Transmit (active-HIGH) enables data also available without bushold feature (74LVT245). from A ports to B ports; Receive (active-LOW) enables Live insertion/extraction permitted data from B ports to A ports. The Output Enable input, Power Up/Down high impedance provides glitch-free when HIGH, disables both A and B ports by placing them in bus loading a HIGH Z condition. Outputs source/sink, −32 mA/+64 mA The LVTH245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.Latch-up performance exceeds 500 mA These transceivers are designed for low-voltage (3.3V)ESD performance: V applications, but with the capability to provide a TTL CC Human-body model > 2000V interface to a 5V environment. The LVT245 and LVTH245 Machine model > 200V are fabricated with an advanced BiCMOS technology to Charged-device model > 1000V achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
