Quad 2-Input Multiplexer Three-State/ Non-Inverting
CD54/74AC257, CD54/74ACT257, CD74ACT258 SCHS248A Quad 2-Input Multiplexer August 1998 - Revised May 2000 with Three-State Outputs Features Description • ’AC257, ’ACT257. . . . . . . . . . . . . Non-Inverting Outputs The ’AC257, ’ACT257 and CD74ACT258 are quad 2-input multiplexers with three-state outputs that utilize Advanced • CD74ACT258 . . . . . . . . . . . . . . . . . . . Inverting Outputs CMOS Logic technology. Each of these devices selects four bits of data from two sources under the control of a common • Buffered Inputs Select input (S). The Output Enable (OE) is active LOW. • Typical Propagation Delay When OE is HIGH, all of the outputs (Y or Y) are in the high- o - 4.4ns at V = 5V, T = 25 C, C = 50pF impedance state regardless of all other input conditions. CC A L • Exceeds 2kV ESD Protection MIL-STD-883, Method Moving data from two groups of registers to four common 3015 output buses is a common use of the ’AC257, ’ACT257, and CD74ACT258.
