DESCRIPTION
The 74LCXHR162245 is a low voltage CMOS 16
BIT BUS TRANSCEIVER (3-STATE) fabricated
with sub-micron silicon gate and double-layer
metal wiring C2MOS technology. It is ideal for low
power and high speed 3.3V applications; it can be
interfaced to 5V signal environment for both inputs
and outputs.
This IC is intended for two-way asynchronous
communication between data buses; the direction
of data transmission is determined by DIR input.
The two enable inputs nG can be used to disable
the device so that the buses are effectively isolat-
ed.
Bus hold on data inputs is provided in order to
eliminate the need for external pull-up or
pull-down resistor.
All outputs, which are designed to sink up to
12mA, include 26resistors to reduce overshoot
and undershoot.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.

1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch-
ing in the same direction, either HIGH or LOW (tOSLH = | tPLHm - tPLHn|, tOSHL = | tPHLm - tPHLn|)

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/16 (per
circuit)
