74ACT253PCX中文资料仙童半导体数据手册PDF规格书

General Description

The AC/ACT253 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.

Features

■ ICC and IOZ reduced by 50

■ Multifunction capability

■ Noninverting 3-STATE outputs

■ Outputs source/sink 24 mA

■ ACT253 has TTL-compatible inputs
