MC74LCX16240

The MC74LCX16240 is a high performance, inverting 16bit buffer operating from a 2.7 to 3.6V supply. The device is nibble controlled. Each nibble has separate Output Enable inputs which can be tied together for full 16bit 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 5.5V allows MC74LCX16240 inputs to be safely driven from 5V devices. The LCX16240 is suitable for memory address driving and all TTL level bus
oriented transceiver applications.

Current drive capability is 24mA at the outputs. The Output Enable (OEn) inputs, when HIGH, disable the outputs by placing them in a HIGH Z condition.

• ESD Performance: Human Body Model >2000V; Machine Model >200V The MC74LCX16240 contains sixteen inverting buffers with 3state 5Vtolerant outputs. The device is nibble controlled with each nibble functioning identically, but independently. The control pins may be tied together to obtain full 16bit operation. The 3state 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.
