54LCX16244 Datasheet | National Semiconductor

Description The LCX16244 contains sixteen non-inverting buffers with TRI-STATE ® outputs designed to be employed as a memory and address driver, clock driver, or bus oriented transmitter/ receiver. The device is nibble controlled. Each nibble has separate TRI-STATE control inputs which can be shorted together for full 16-bit operation. The LCX16244 is designed for low voltage (3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX16244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

Pin Descriptions Pin Names OEn I0- I15 O0- O15 Inputs Outputs Description Output Enable Input (Active Low) Functional Description The LCX16244 contains sixteen non-inverting buffers with TRI-STATE standard outputs. The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation. The TRI-STATE outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are in bi-state mode. When OEn is HIGH, the outputs are in the high impedance mode, but this does not interfere with entering new data into the...
