This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the
SN74LVCR162245
16-BIT BUS TRANSCEIVER
WITH 3-STATE OUTPUTS
SCES047E – AUGUST 1995 – REVISED MARCH 2005
Member of the Texas Instruments Widebus
Family
Operates From 2.7 V to 3.6 V
Inputs Accept Voltages to 5.5 V
Max tpd of 8.5 ns at 3.3 V
Typical VOLP (Output Ground Bounce) < 0.8 V
at VCC = 3.3 V, TA = 25°C
Typical VOHV (Output VOH Undershoot) > 2 V at
VCC = 3.3 V, TA = 25°C
Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
All Outputs Have Equivalent 26-
Series
Resistors, So No External Resistors Are
Required
Latch-Up Performance Exceeds 250 mA Per
JEDEC Standard JESD-17
ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
– 200-V Machine Model (A115-A)
This 16-bit (dual-octal) noninverting bus transceiver is
designed for 2.7-V to 3.6-V VCC operation.
The SN74LVCR162245 is designed for asynchronous
communication
between
data
buses.
The
control-function implementation minimizes external
timing requirements.
A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR)
input. The output-enable (OE) input can be used to disable the device so that the buses effectively are isolated.
All outputs, which are designed to sink up to 12 mA, include 26-
resistors to reduce overshoot and undershoot.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullup or
pulldown resistors with the bus-hold circuitry is not recommended. The bus-hold circuitry is part of the input
circuit and is not disabled by OE or DIR.
