MC74LCX16240_12 Datasheet, PDF (1/8 Pages) ON Semiconductor – Low-Voltage CMOS 16-Bit Buffer

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 V_I 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.
