1 / 8 page SN74LVC157A QUADRUPLE 2-LINE TO 1-LINE DATA SELECTOR/MULTIPLEXER SCAS292G – JANUARY 1993 – REVISED OCTOBER 1998 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D EPIC™ (Enhanced-Performance Implanted CMOS) Submicron Process D Typical VOLP (Output Ground Bounce) < 0.8 V at VCC = 3.3 V, TA = 25°C D Typical VOHV (Output VOH Undershoot) > 2 V at VCC = 3.3 V, TA = 25°C D Inputs Accept Voltages to 5.5 V D ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0) D Latch-Up Performance Exceeds 250 mA Per JESD 17 D Package Options Include Plastic Small-Outline (D), Shrink Small-Outline (DB), and Thin Shrink Small-Outline (PW) Packages description This quadruple 2-line to 1-line data selector/multiplexer is designed for 1.65-V to 3.6-V VCC operation. The SN74LVC157A features a common strobe (G) input. When the strobe is high, all outputs are low. When the strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The device provides true data. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment. The SN74LVC157A is characterized for operation from –40 °C to 85°C.
