SCES635B – JULY 2005 – REVISED APRIL 2015 SN74LVCH16T245 16-bit Dual-supply Bus Transceiver
With Configurable Level-Shifting/Voltage Translation and Tri-State Outputs
1 Features 3 Description This 16-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 Control Inputs VIH/VIL Levels are Referenced to
VCCA Voltage
VCC Isolation Feature – If Either VCC Input is at
GND, All Outputs are in the High-Impedance State
Overvoltage-Tolerant Inputs and Outputs Allow
Mixed-Voltage-Mode Data Communications
Fully Configurable Dual-Rail Design Allows Each
Port to Operate Over the Full 1.65 V to 5.5 V …
