74VCX16827
Low Voltage 20-Bit Buffer/Line Driver with
3.6V Tolerant Inputs and Outputs
General Description
The VCX16827 contains twenty non-inverting buffers with
3-STATE outputs to be employed as a memory and
address driver, clock driver, or bus oriented transmitter/
receiver carrying parity. The device is byte controlled. Each
byte has NOR output enables for maximum control flexibil-
ity.
The 74VCX16827 is designed for low voltage (1.2V to
3.6V) VCC applications with I/O capability up to 3.6V.
The 74VCX16827 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
Features
s 1.2V to 3.6V VCC supply operation
s 3.6V tolerant inputs and outputs
s tPD
2.5 ns max for 3.0V to 3.6V VCC
s Power-off high impedance inputs and outputs
s Supports live insertion and withdrawal (Note 1)
s Static Drive (IOH/IOL)
±24 mA @ 3.0V VCC
s Uses patented noise/EMI reduction circuitry
s Latch-up performance exceeds 300 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
Note 1: To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
