SN74AVC16T245
SCES551E – FEBRUARY 2004 – REVISED NOVEMBER 2015
SN74AVC16T245 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
SN74AVC16T245 device is optimized to operate with
VCCA/VCCB set at 1.4 V to 3.6 V. The device is
operational with VCCA/VCCB as low as 1.2 V. The A
port is designed to track VCCA. VCCA accepts any
supply voltage from 1.2 V to 3.6 V. The B port is
designed to track VCCB. VCCB accepts any supply
voltage from 1.2 V to 3.6 V. This allows for universal
low-voltage bidirectional translation between any of
the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage
nodes.
