74LCXH162373
Low Voltage 16-Bit Transparent Latch
with Bushold and 26Series Resistor Outputs
General Description
The LCXH162373 contains sixteen non-inverting latches
with 3-STATE outputs and is intended for bus oriented
applications. The device is byte controlled. The flip-flops
appear transparent to the data when the Latch Enable (LE)
is HIGH. When LE is LOW, the data that meets the setup
time is latched. Data appears on the bus when the Output
Enable (OE) is LOW. When OE is HIGH, the outputs are in
a high impedance state.
The LCXH162373 is designed for low voltage (2.5V or
3.3V) VCC applications with capability of interfacing to a 5V
signal environment. The 26series resistor helps reduce
output overshoot and undershoot.
The LCXH162373 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
The LCXH162373 data inputs include active bushold cir-
cuitry, eliminating the need for external pull-up resistors to
hold unused or floating data inputs at a valid logic level.
Features
s 5V tolerant control inputs and outputs
s 2.3V–3.6V VCC specifications provided
s Equivalent 26series resistors on outputs
s Bushold on inputs eliminates the need for external
pull-up/pull-down resistors
s 6.2 ns tPD max (VCC = 3.3V), 20 µA ICC max
s Power down high impedance inputs and outputs
s ±12 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
s Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA) (Preliminary)

Note 2: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The Recom-
mended Operating Conditionstable will define the conditions for actual device operation.
Note 3: IO Absolute Maximum Rating must be observed.
Note 4: Floating or unused control inputs must be HIGH or LOW.
