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. The LVX4245 is suitable for mixed voltage applications such as laptop computers using 3.3V CPU’s and 5V LCD displays. 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 Description 24-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300” Wide 24-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, 0.15...
