CD54/74AC257, CD54/74ACT257, CD74ACT258 Data sheet acquired from Harris Semiconductor SCHS248A Quad 2-Input Multiplexer with Three-State Outputs August 1998 - Revised May 2000 Features Description • ’AC257, ’ACT257. . . . . . . . . . . . . Non-Inverting Outputs The ’AC257, ’ACT257 and CD74ACT258 are quad 2-input multiplexers with three-state outputs that utilize Advanced CMOS Logic technology. Each of these devices selects four bits of data from two sources under the control of a common Select input (S). The Output Enable (OE) is active LOW. When OE is HIGH, all of the outputs (Y or Y) are in the highimpedance state regardless of all other input conditions. • CD74ACT258 . . . . . . . . . . . . . . . . . . . Inverting Outputs • Buffered Inputs • Typical Propagation Delay - 4.4ns at VCC = 5V, TA = 25oC, CL = 50pF • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 Moving data from two groups of registers to four common output buses is a common use of the ’AC257, ’ACT257, and CD74ACT258. The state of the Select input determines the particular register from which the data comes. The ’AC257, ’ACT257 and CD74ACT258 can also be used as function generators. • SCR-Latchup-Resistant CMOS Process and Circuit Design • Speed of Bipolar FAST™/AS/S with Significantly Reduced Power Consumption • Balanced Propagation Delays Ordering Information • AC Types Feature 1.5V to 5.5V Operation and Balanced Noise Immunity at 30% of the Supply PART NUMBER • ±24mA Output Drive Current - Fanout to 15 FAST™ ICs TEMP.
