Description

The MC74LCX257DTR2G is a high performance, quad 2−input multiplexer with 3−state outputs operating from a 2.3 to 3.6 V supply.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 MC74LCX257DTR2G inputs to be safely driven from 5.0 V devices.Four bits of data from two sources can be selected using the Select input. The four outputs present the selected data in the true (non−inverted) form. The outputs may be switched to a high impedance state by placing a logic HIGH on the Output Enable (OE) input. Current drive capability is 24 mA at the outputs. MC74LCX257DTR2G Features • Designed for 2.3 to 3.6 V VCC Operation• 5.0 V Tolerant − Interface Capability with 5.0 V TTL Logic• Supports Live Insertion and Withdrawal• IOFF Specification Guarantees High Impedance When VCC = 0 V• LVTTL Compatible• LVCMOS Compatible• 24 mA Balanced Output Sink and Source Capability• Near Zero Static Supply Current in All Three Logic States (10 A) Substantially Reduces System Power Requirements• Latchup Performance Exceeds 500 mA• ESD Performance: Human Body Model >2000 V Machine Model >200 V• Pb−Free Packages are Available*
