Product Overview: 74HC257PW from NXP

The 74HC257PW is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). It is fabricated with silicon gate CMOS technology which ensures that it has the high noise immunity and low power consumption typical of CMOS integrated circuits, along with speeds approaching those of LSTTL devices.

Key Features

• Logic Type: Quad 2-Input Multiplexer
• Supply Voltage Range: 2.0 to 6.0 V
• Operating Temperature: -40°C to +125°C
• Package: TSSOP16
• Output Capability: Standard
• ICC Category: MSI

Functional Description

The 74HC257PW features four multiplexers with common select and enable inputs. Each multiplexer has two input lines (A0 and A1, B0 and B1, C0 and C1, D0 and D1) and one output line (Y0, Y1, Y2, Y3). A select input (S) and an enable input (E) control which of the inputs is connected to the corresponding output. When the enable input is high, all outputs are forced to a high-impedance OFF-state.

Applications

This device is suitable for various applications, including:

• Function generator
• Binary to 1-of-4 decoder
• Data routing
• Signal gating
