SN74AVC4T774
SCES693E – FEBRUARY 2008 – REVISED OCTOBER 2017
SN74AVC4T774 4-Bit Dual-Supply Bus Transceiver With Configurable Voltage-Level
Shifting and 3-State Outputs With Independent Direction Control Inputs
1 Features
3 Description
•
This 4-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 1.2 V to 3.6 V. The B port is designed to
track VCCB. VCCB accepts any supply voltage from 1.2
to 3.6 V. The SN74AVC4T774 is optimized to operate
with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational
with VCCA/VCCB as low as 1.2 V. This allows for
universal
low-voltage
bi-directional
translation
between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and
3.3-V voltage nodes.
