74LVX4245 - 8-Bit Dual Supply Translating Transceiver

General Description

The LVX4245 is a dual-supply, 8-bit translating transceiver that is designed to interface between a 5V bus and a 3V bus in a mixed 3V/5V supply environment.

The Transmit/ Receive (T/R) input determines the direction of data flow.

Key Features

  • s Bidirectional interface between 5V and 3V buses s Control inputs compatible with TTL level s 5V data flow at A Port and 3V data flow at B Port s Outputs source/sink 24 mA at 5V bus; 12 mA at 3V bus s Guaranteed simultaneous switching noise level and dynamic threshold performance s Implements patented EMI reduction circuitry s Functionally compatible with the 74 series 245 Ordering Code: Order Number 74LVX4245WM 74LVX4245QSC 74LVX4245MTC Package Number M24B MQA24 MTC24 Package.

74LVX4245 8-Bit Dual Supply Translating Transceiver with 3-STATE Outputs January 1993 Revised July 1999 74LVX4245 8-Bit Dual Supply Translating Transceiver with 3-STATE Outputs General Description The LVX4245 is a dual-supply, 8-bit translating transceiver that is designed to interface between a 5V bus and a 3V bus in a mixed 3V/5V 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 5V bus; the B Port interfaces with the 3V bus.
