A20131 - CD74HCT253E CMOS Logic Dual 4-Input Multiplexer (Harris)

The CD74HCT253E is a dual 4-to-1 line selector/multiplexer having three-state outputs. One of four sources for each section is selected by the common select inputs, S0 and S1. When the output enable (1OE, 2OE) is HIGH, the output is in the high-impedance state.Features:Common Select InputsSeparate Output-Enable InputsThree-State OutputsFanout (Over Temperature Range):- Standard Outputs . . . 10 LSTTL Loads- Bus Driver Outputs . . .15 LSTTL LoadsWide Operating Temperature Range . . . -55°C to 125°CBalanced Propagation Delay and Transition TimesSignificant Power Reduction Compared to LSTTL Logic ICs4.5V to 5.5V OperationDirect LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min)CMOS Input Compatibility, Il = 1?A at VOL, VOH16 pin DIP.
