INTEGRATED CIRCUITS 74LV157 Quad 2-input multiplexer Product specification Supersedes data of 1997 May 15 IC24 Data Handbook 1998 Apr 30 Philips Semiconductors Philips Semiconductors Product specification Quad 2-input multiplexer 74LV157 FEATURES • Optimized for low voltage applications: 1.0 to 3.6 V • Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V • Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, • Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, • Output capability: standard • ICC category: MSI DESCRIPTION The 74LV157 is a low-voltage CMOS device and is pin and function compatible with 74HC/HCT157. The 74LV157 is a quad 2-input multiplexer which selects 4 bits of data from two sources under the control of a common data select input (S). Tamb = 25°C Tamb = 25°C The four outputs present the selected data in the true (non-inverted) form. The enable input (E) is active LOW. When E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all other input conditions. Moving the data from two groups of registers to four common output buses is a common use of the 74LV157. The state of the common data select input (S) determines the particular register from which the data comes. It can also be used as function generator. The device is useful for implementing highly irregular logic by generating any four of the 16 different functions of two variables with one variable common. The 74LV157 is the logic implementation of a 4-pole, 2-position switch, where the position of the switch is determined by the logic levels applied to S.
