MC74LCX16240

Low−Voltage CMOS

16−Bit Buffer

With 5 V−Tolerant Inputs and Outputs

(3−State, Inverting)

The MC74LCX16240 is a high performance, inverting

16−bit buffer operating from a 2.3 V to 3.6 V supply. The device is

nibble controlled. Each nibble has separate Output Enable inputs

which can be tied together for full 16−bit operation. High impedance

TTL compatible inputs significantly reduce current loading to input

drivers while TTL compatible outputs offer improved switching noise

performance. A VI specification of 5.5 V allows MC74LCX16240

inputs to be safely driven from 5.0 V devices. The LCX16240 is

suitable for memory address driving and all TTL level bus oriented

transceiver applications.

Current drive capability is 24 mA at the outputs. The Output Enable

(OEn) inputs, when HIGH, disable the outputs by placing them in a

HIGH Z condition.

The MC74LCX16240 contains sixteen inverting buffers with

3−state 5.0 V tolerant outputs. The device is nibble controlled with

each nibble functioning identically, but independently. The control

pins may be tied together to obtain full 16−bit operation. The 3−state

outputs are controlled by an Output Enable (OEn) input for each

nibble. When OEn is LOW, the outputs are on. When OEn is HIGH,

the outputs are in the high impedance state.
