Low-Voltage CMOS

16-Bit Buffer

With 5V-Tolerant Inputs and Outputs

(3-State, Inverting)

MC74LCX16240

The MC74LCX16240 is a high performance, inverting 16–bit 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 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 5.5V 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.

• Designed for 2.7 to 3.6V VCC Operation

• 5V Tolerant — Interface Capability With 5V TTL Logic

• Supports Live Insertion and Withdrawal

• IOFF Specification Guarantees High Impedance When VCC = 0V

• LVTTL Compatible

• LVCMOS Compatible

• 24mA Balanced Output Sink and Source Capability

• Near Zero Static Supply Current in All Three Logic States (10µA)

Substantially Reduces System Power Requirements

• Latchup Performance Exceeds 500mA

• ESD Performance: Human Body Model >2000V; Machine Model >200V

The MC74LCX16240 contains sixteen inverting buffers with 3–state

5V–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.
