54AC253 - 54ACT253 Dual 4-Input Multiplexer with TRI-STATE Outputs August 1998 54AC253 - 54ACT253 Dual 4-Input Multiplexer with TRI-STATE ® Outputs General Description The ’AC/’ACT253 is a dual 4-input multiplexer with TRI-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. n n n n n Multifunction capability Noninverting TRI-STATE outputs Outputs source/sink 24 mA ’ACT253 has TTL-patible inputs Standard Military Drawing (SMD) - ’AC253: 5962-87693 -...
