Product Summary
The SN74LVC1T45DBVR is a single-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs. The SN74LVC1T45DBVR uses two separate configurable power-supply rails. The SN74LVC1T45DBVR is designed for asynchronous communication between data buses. The SN74LVC1T45DBVR transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input.
Parametrics
SN74LVC1T45DBVR absolute maximum 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-impedance 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) Output clamp current, IOK (VO< 0) : -50mA; (7) Continuous output current, IO: ±50mA; (8) Continuous current through Vcc or GND: ±100mA.
