74LVC1G157
Single 2-input multiplexer
Rev. 03 -- 12 July 2007 Product data sheet
1. General description
The 74LVC1G157 is a single 2-input multiplexer which select data from two data inputs (I0 and I1) under control of a common data select input (S). The state of the common data select input determines the particular register from which the data comes. The output (Y) presents the selected data in the true (non-inverted) form. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V applications. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. Schmitt-trigger action at all inputs makes the circuit highly tolerant to slower input rise and fall times.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed. When VCC = 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation. For SC-88 and SC-74 packages: above 87.5 C the value of Ptot derates linearly with 4.0 mW/K. For XSON6 packages: above 45 C the value of Ptot derates linearly with 2.4 mW/K.

Typical values are measured at Tamb = 25 C and VCC = 1.8 V, 2.5 V, 2.7 V, 3.3 V and 5.0 V respectively. tpd is the same as tPLH and tPHL. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = number of inputs switching; (CL x VCC2 x fo) = sum of the outputs.
