MC74AC253, MC74ACT253 Dual 4Input Multiplexer with 3State Outputs The MC74AC253/74ACT253 is a dual 4input multiplexer with 3state outputs. It can select two bits of data from four sources using common select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus oriented systems. http://onsemi.com w Multifunctional Capability Noninverting 3State Outputs Outputs Source/Sink 24 mA ′ACT253 Has TTL Compatible Inputs These devices are available in Pbfree package(s). Specifications herein apply to both standard and Pbfree devices. Please see our website at www.onsemi.com for specific Pbfree orderable part numbers, or contact your local ON Semiconductor sales office or representative.
