The 74LVX3245MTCX from onsemi is an 8-bit dual-supply bidirectional translating transceiver designed to interface between 3V and 5V buses in mixed-voltage systems. The A port interfaces with the lower-voltage 3V bus, while the B port interfaces with the 5V bus, enabling eight channels of parallel bidirectional logic-level translation.
A dedicated Transmit/Receive (T/R#) input controls the direction of data flow. When T/R# is HIGH, data is transferred from Port A to Port B; when T/R# is LOW, data is transferred from Port B to Port A. An Output Enable (OE) input places both ports into a high-impedance state when disabled, allowing easy bus isolation and shared-bus operation.
Under the recommended operating conditions, VCCA operates from 2.7V to 3.6V and VCCB from 4.5V to 5.5V. The device features TTL-compatible inputs and can source or sink up to approximately 24mA at its outputs. It also incorporates proprietary EMI-reduction circuitry and is functionally compatible with 74-series 245 bus transceivers.
The 74LVX3245MTCX is supplied in a 24-pin TSSOP package with a 4.4mm body width and is rated for operation from -40°C to +85°C. The MTCX ordering option is supplied in 2500-piece tape-and-reel packaging, and onsemi currently lists the part as Active.
