74LCX257 Datasheet Low Voltage Quad 2-input Multiplexer

Manufacturer: Fairchild (now onsemi)

Overview: 74LCX257 Low Voltage Quad 2-Input Multiplexer with 5V Tolerant Inputs and Outputs May 1995 Revised September 2000 74LCX257 Low Voltage Quad 2-Input Multiplexer with 5V Tolerant Inputs and.

General Description

The LCX257 is a quad 2-input multiplexer with 3-STATE outputs.

Four bits of data from two sources can be selected using a Common Data Select input.

The four outputs present the selected data in true (non inverted) form.

Key Features

  • s 5V tolerant inputs and outputs s 2.3V.
  • 3.6V VCC specifications provided s 6.0 ns tPD max (VCC = 3.3V, In → Zn), 10 µA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s ESD performance: Human body model > 2000V Machine model > 200V Note 1: To ensure the high-impedance state during power up or down, OE should be tied to VCC through a pull-up resist.
