Low Voltage Octal Transparent Latch with 5V Tolerant
Inputs and Outputs
The LCX373 consists of eight latches with 3-STATE out-
puts for bus organized system applications. The device is
designed for low voltage (3.3V or 2.5V) VCC applications
with capability of interfacing to a 5V signal environment.
The LCX373 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 8.0 ns tPD max (VCC = 3.3V), 10 µA ICC max
s Power-down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 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
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
