Part Details:

74LVQ157 LOW VOLTAGE QUAD 2 CHANNEL MULTIPLEXER s HIGH SPEED: tPD = 7 ns (TYP.) at VCC = 3.3 V s COMPATIBLE WITH TTL OUTPUTS s LOW POWER DISSIPATION:ICC = 4 µA (MAX.) at TA=25°C s LOW NOISE:V SOP TSSOP OLP = 0.2V (TYP.) at VCC = 3.3V s 75 TRANSMISSION LINE OUTPUT DRIVE CAPABILITY Table 1: Order Codes s SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 12mA (MIN) at VCC = 3.0 V PACKAGE T & R s PCI BUS LEVELS GUARANTEED AT 24 mA SOP 74LVQ157MTR s BALANCED PROPAGATION DELAYS: TSSOP 74LVQ157TTR tPLH tPHL s OPERATING VOLTAGE RANGE:VCC(OPR) = 2V to 3.6V (1.2V Data Retention) It consists of four 2-input digital multiplexers with s PIN AND FUNCTION COMPATIBLE WITH common select and strobe inputs. When STROBE 74 SERIES 157 input is held high selection of data is inhibit and all s IMPROVED LATCH-UP IMMUNITY the outputs become low. The SELECT decodingdetermines whether the A or B inputs get routed to DESCRIPTION their corresponding Y outputs. The 74LVQ157 is a low voltage CMOS QUAD All inputs and outputs are equipped with 2-CHANNEL MULTIPLEXER fabricated with protection circuits against static discharge, giving sub-micron silicon gate and double-layer metal them 2KV ESD immunity and transient excess wiring C2MOS technology. It is ideal for low power voltage. and low noise 3.3V applications. Figure 1: Pin Connection And IEC Logic Symbols Rev. 5
