Functional Descriptions

The LCXP16245 contains sixteen non-inverting bidirec-

tional buffers with 3-STATE outputs. the device is byte con-

trolled. Each byte has separate control inputs which can be

shorted together for full 16-bit operation. The T/R inputs

determine the direction of data flow through the device.

The OE inputs disable both the A and B ports by placing

them in a high impedance state. The pulldown resistor

(30K

: normal) to GND is active only when the outputs are

3-STATED (OE

HIGH). When the outputs become active

(OE

LOW) the resistor is removed from the circuit.
