IDT74LVC16540A
DESCRIPTION:
This 16-bit buffer driver is built using advanced dual metal CMOS
technology. The 3-state control gate is a 2-input AND gate with active-low
inputs so that if either output-enable (OE1 or
OE2)
input is high, all
corresponding outputs are in the high-impedance state. To ensure the high-
impedance state during power up or power down,
OE
should be tied to Vcc
through a pullup resistor; the minimum value of the resistor is determined
by the current-sinking capabiltiy of the driver.
All pins of this 16-bit buffer/line driver can be driven from either 3.3V or
5V devices. This feature allows the use of this device as a translator in a
mixed 3.3V/5V supply system.
The LVC16540A has been designed with a 鹵24mA output driver. The
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
Drive Features for LVC16540A:
鈥?High Output Drivers: 鹵24mA
鈥?Reduced system switching noise
APPLICATIONS:
鈥?5V and 3.3V mixed voltage systems
鈥?Data communication and telecommunication systems
