Product Summary

The SN74LVC2T45DCUR is a dual-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs. The SN74LVC2T45DCUR uses two separate configurable power-supply rails. The SN74LVC2T45DCUR is designed for asynchronous communication between data buses.

Parametrics

SN74LVC2T45DCUR absolute ratings: (1) supply voltage range, VCCA and VCCB: -0.5 to 6.5V; (2) Input voltage range, VI: -0.5 to 6.5V; (3) Voltage range applied to any output in the high-impendance or power-off state, VO: -0.5 to 6.5V; (4) Voltage range applied to any output in the high or low state, VO: -0.5 to VCCA +0.5V (A port) , -0.5 to VCCB +0.5V (B port) ; (5) Input clamp current, IIK (VI﹤0) : -50mA; (6) Continuous output current, IO: ±50mA; (7) Continuous current through Vcc or GND: ±100mA; (8) Storage temperature range, Tstg: -65 to 150°C.

Features

SN74LVC2T45DCUR features: (1) available in the Texas instruments Nanostar and NanoFree Packages; (2) Fully configurable dual-rail design allows each port to operate over the full 1.65V to 5.5V power-supply range; (3) Vcc Isolatin feature -If either Vcc input is at GND , both ports are in the hig-impedance state; (4) DIR input circuit referenced to VccA; (5) low power consumption , 10μA max Icc; (6) ±24mA output drive at 3.3V.
