Overview
74LVX3245 — 8-Bit Dual-Supply Translating Transceiver with 3-State Outputs April 2016 74LVX3245 8-Bit, Dual-Supply Translating Transceiver with 3-State Outputs Features  Bidirectional Interface Between 3 V and 5 V Buses  Inputs Compatible with TTL Level  3 V Data Flow at A-Port and 5 V Data Flow at B- Port  Outputs Source / Sink: 24 mA  Guaranteed Simultaneous Switching Noise Level and Dynamic Threshold Performance  Implements Proprietary EMI Reduction Circuitry  Functionally Compatible with the 74 Series 245 Description The 74LVX3245 is a dual-supply, 8-bit translating transceiver designed to interface between a 3 V bus and a 5 V bus in a mixed 5 V supply environment.
The Transmit/ Receive (T/R¯ ) input determines the direction of data flow.
Transmit (active-HIGH) enables data from A-ports to B-ports; receive (active-LOW) enables data from B-ports to A-ports.
The output enable input, when HIGH, disables both A- and B-ports by placing them in a high-impedance condition.
The A-port interfaces with the 3 V bus; the B-port interfaces with the 5 V bus.
The 74LVX3245 is suitable for mixed-voltage applications, such as notebook computers using 3.
3 V CPU and 5V peripheral components.
