74VCX16373
Low Voltage 16-Bit Transparent Latch
with 3.6V Tolerant Inputs and Outputs
General Description
Features
■ 1.2V to 3.6V VCC supply operation
The VCX16373 contains sixteen non-inverting latches with
3-STATE outputs and is intended for bus oriented applica-
tions. The device is byte controlled. The flip-flops appear to
be 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.
■ 3.6V tolerant inputs and outputs
■ tPD (In to On)
3.0 ns max for 3.0V to 3.6V VCC
■ Power-off high impedance inputs and outputs
■ Support live insertion and withdrawal (Note 1)
■ Static Drive (IOH/IOL
)
The 74VCX16373 is designed for low voltage (1.2V to
3.6V) VCC applications with I/O compatibility up to 3.6V.
24 mA @ 3.0V VCC
The 74VCX16373 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
■ Uses patented noise/EMI reduction circuitry
■ Latch-up performance exceeds 300 mA
■ ESD performance:
Human body model 2000V
Machine model 200V
■ Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA) (Preliminary)
Note 1: To ensure the high-impedance state during power up or power
down, OE should be tied to V
through a pull-up resistor; the minimum
CC
value of the resistor is determined by the current-sourcing capability of the
driver.
