? semiconductor components industries, llc, 2005 january, 2005 ? rev. 4 1 publication order number: mc74lcx258/d mc74lcx258 low-voltage cmos quad 2-input multiplexer with 5 v?tolerant inputs and outputs (3?state, inverting) the mc74lcx258 is a high performance, quad 2?input inverting 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 v i specification of 5.5 v allows mc74lcx258 inputs to be safely driven from 5 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 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. features ? designed for 2.3 to 3.6 v v cc operation ? 5 v tolerant ? interface capability with 5 v ttl logic ? supports live insertion and withdrawal ? i off specification guarantees high impedance when v cc = 0 v ? ttl compatible ? cmos 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* *for additional information on our pb?free strategy and soldering details, please download the on semiconductor soldering and mounting techniques reference manual, solderrm/d. marking diagrams a = assembly location l, wl = wafer lot y = year w, ww = work week soic?16 d suffix case 751b lcx258 awlyww lcx 258 alyw tssop?16 dt suffix case 948f soeiaj?16 m suffix case 966 74lcx258 alyw 16 1 16 16 1 1 16 1 16 1 16 1 see detailed ordering and shipping information in the package dimensions section on page 4 of this data sheet. ordering information http://onsemi.com
