74VCX162827
Low Voltage 20-Bit Buffer/Line Driver with 3.6V Tolerant
Inputs and Outputs and 26Ω Series Resistors in the
Outputs
General Description
Features
The VCX162827 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. The device is byte controlled. Each byte has NOR
output enables for maximum control flexibility.
s 1.65V–3.6V VCC supply operation
s 3.6V tolerant inputs and outputs
s 26Ω series resistors in outputs
s tPD
The 74VCX162827 is designed for low voltage (1.65V to
3.6V) VCC applications with I/O capability up to 3.6V. The
VCX162827 is also designed with 26Ω resistors in the out-
puts.
The 74VCX162827 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
3.4 ns max for 3.0V to 3.6V VCC
4.1 ns max for 2.3V to 2.7V VCC
8.2 ns max for 1.65V to 1.95V VCC
s Power-off high impedance inputs and outputs
s Supports live insertion and withdrawal (Note 1)
s Static Drive (IOH/IOL)
±12 mA @ 3.0V VCC
±8 mA @ 2.3V VCC
±3 mA @ 1.65V VCC
www.DataSsheUet4sUe.csompatented 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.
