The 74LVC257A is a quad 2-input multiplexer with 3-state outputs. This device accepts a wide supply voltage range from 1.2V to 3.6V.
Both 3.3V and 5V devices can drive inputs, enabling this device to operate as a translator in a mixed 3.3V and 5V system environment. All inputs support Schmitt-Trigger action, which allows the circuit to tolerate slower input rise and fall times.
The output enable input (OE) is active-low. When OE held high, the 1Y to 4Y outputs are in high-impedance state no matter what the conditions of the inputs are. When OE is held low, four bits of data are selected from one of two sources that are determined by the state of the common data selection input (S), and are routed to the four outputs. The four outputs present the true (non-inverting) selected data. The S input can also be used as a function generator.
The 74LVC257A is available in Green TQFN-3.5×4-16L, SOIC-16 and TSSOP-16 packages. It operates over a temperature range of -40℃ to +125℃.
