MC74AC253M中文资料安森美半导体数据手册PDF规格书

The MC74AC253/74ACT253 is a dual 4−input multiplexer with 3−state 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.

• Multifunctional Capability

• Noninverting 3−State Outputs

• Outputs Source/Sink 24 mA

• ′ACT253 Has TTL Compatible Inputs

• These devices are available in Pb−free package(s). Specifications herein
