- 74ACT253 Dual 4-Input Multiplexer with 3-STATE Outputs
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 mon 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 s ICC and IOZ reduced by 50% s Multifunction capability s Non inverting 3-STATE outputs s Outputs source/sink 24 mA s ACT253 has TTL-patible inputs
