DESCRIPTION/ORDERING INFORMATION
This 16-bit noninverting bus transceiver uses two
separate configurable power-supply rails. The A port
is designed to track V
CCA
. V
CCA
accepts any supply
voltage from 1.65 V to 5.5 V. The B port is designed
to track V
. V
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.

16-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
SCES635A–JULY 2005–REVISED AUGUST 2005
The SN74LVCH16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V
CCA
.
The SN74LVCH16T245 is designed for asynchronous communication between two data buses. The logic levels
of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the
A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A
bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs
are activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW
level applied to prevent excess I
CC
and I
CCZ
.
