CD74AC151, CD74ACT151 Data sheet acquired from Harris Semiconductor SCHS236 8-Input Multiplexer September 1998 Features Description • Buffered Inputs • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 The CD74AC151 and CD74ACT151 are 8-input digital multiplexers that utilize the Harris Advanced CMOS Logic technology. They have three binary control inputs (S0, S1, and S2) and an active-LOW Enable (E) input. The three binary inputs select 1 of 8 channels. The output is both inverting (Y) and non-inverting (Y). • SCR-Latchup-Resistant CMOS Process and Circuit Design Ordering Information • Typical Propagation Delay - 6ns at VCC = 5V, TA = 25oC, CL = 50pF [ /Title (CD74 AC151 , CD74 ACT15 1) /Subject (8Input Multiplexer) /Autho r () /Keywords (Harris Semiconductor, Advan ced CMOS ) /Creator () /DOCI NFO pdfmark • Speed of Bipolar FAST™/AS/S with Significantly Reduced Power Consumption PART NUMBER TEMP.
