Product Summary

The SN74LVC1T45DBVT is a type of single-bit noninverting bus transceiver which uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.

Parametrics

SN74LVC1T45DBVT maximum ratings: (1)Supply voltage range: 0.5 V to 6.5 V; (2)Input voltage range: 0.5 V to 6.5 V; (3)Voltage range applied to any output in the high-impedance or power-off state: 0.5 V to 6.5 V; (4)Voltage range applied to any output in the high or low state: 0.5 V to VCCA + 0.5V; (5)B port: 0.5 V to VCCB + 0.5V; (6)Input clamp current, IIK (VI < 0): 50 mA; (7)Output clamp current, IOK (VO < 0): 50 mA; (8)Continuous output current, IO; ±50 mA; (9)Continuous current through VCC or GND: ±100 mA.

Features

SN74LVC1T45DBVT 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 1.65 V to 5.5 V Power-Supply Range; (3)VCC Isolation Feature . If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State; (4)DIR Input Circuit Referenced to VCCA; (5)Low Power Consumption, 4-μA Max ICC; (6)±24mA Output Drive at 3.3 V.
