Pericom Semiconductor’s PI74LVTC series of logic circuits are
produced using the Company’s advanced submicron CMOS technology, achieving industry leading speed.
The PI74LVTC16245 is a non-inverting 16-bit Bidirectional Transceiver designed for low-voltage 2.7V to 3.6V VCC operation, with the
capability of interfacing to the 5V system environment. This
tranceiver is designed for asynchronous two-way communication
between data buses. The direction control input pin (xDIR) determines the direction of the data flow through the bidirectional
transceiver. The Direction and Output Enable controls are designed
to operate this device as either two independent 8-bit tranceivers
or one 16-bit transceiver. The output enable (xOE) input, when
HIGH, disables both A and B ports by placing them in
HIGH Z condition.
When Vcc is between 0 to 1.5V during power up or power down, the
outputs of the device are in the high-impedance state. To ensure
the high-impedance state above1.5V, OE should be tied to Vcc
through a pullup resistor; the minimum value of the resistor is
determined by the current sinking capability of the driver.
The device fully supports live-insertion with its Ioff and power-up/
down 3-state. The Ioff circuitry disables the outputs when the power
is off, preventing the backflow of damaging current through the
device. Power-up/down 3-state places the outputs in the
high-impedance state during power up or power down, preventing
driver conflict.

(ICCD) at no output loading and operating at 50% duty cycle, CPD is related to ICCD dynamic operating current by the expression:
