CD74HCT253E Datasheet | Texas Instruments

Data sheet acquired from Harris Semiconductor SCHS170B November 1997 - Revised October 2003 CD74HC253, CD74HCT253 High-Speed CMOS Logic Dual 4-Input Multiplexer [ /Title (CD74 HC253 , CD74 HCT25 3) /Subject (High Speed CMOS Logic Dual 4-Input Multiplexer) Features Description - mon Select Inputs - Separate Output-Enable Inputs - Three-State Outputs - Fanout (Over Temperature Range) - Standard Outputs - - - 10 LSTTL Loads - Bus Driver Outputs - - . . . 15 LSTTL Loads - Wide Operating Temperature Range . . . -55o C to 125o C - Balanced Propagation Delay and Transition Times - Significant Power Reduction pared to LSTTL Logic ICs - HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V - HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic patibility, VIL= 0.8V (Max), VIH = 2V (Min) - CMOS Input patibility, Il ≤ 1µA at VOL, VOH The CD74HC253 and CD74HCT253 are dual 4-to-1 line selector/multiplexers having three-state outputs. One of four sources for each section is selected by the mon select inputs, S0 and S1. When the output enable (1OE, 2OE) is HIGH, the output is in the high-impedance state. Ordering Information PART...
