SCES516K – DECEMBER 2003 – REVISED JUNE 2017 SN74LVC2T45 Dual-Bit Dual-Supply Bus Transceiver With Configurable Voltage
Translation
1 Features 3 Description This dual-bit noninverting bus transceiver 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. 1 Fully Configurable Dual-Rail Design Allows Each
Port to Operate Over the Full 1.65-V to 5.5-V
Power-Supply Range
VCC Isolation Feature – If Either VCC Input Is at
GND, Both Ports Are in the High-Impedance State
DIR Input Circuit Referenced to VCCA
Low Power Consumption, 4-ОјA Max ICC
Available in the Texas Instruments NanoFreeв„ў …
