2 / 8 page www.fairchildsemi.com 2 Connection Diagram Truth Tables H HIGH Voltage Level L LOW Voltage Level X Immaterial (HIGH or LOW, inputs may not float) Z High Impedance Functional Description The 74VCX162240 contains sixteen inverting buffers with 3-STATE outputs. The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of each other. The control pins may be shorted together to obtain full 16-bit operation.The 3-STATE outputs are con- trolled by an Output Enable (OEn) input. When OEn is LOW, the outputs are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the inputs.
