Product Overview: 74HCT253D by NXP Semiconductors

The 74HCT253D is a high-performance, dual 4-channel multiplexer with 3-state outputs from NXP Semiconductors, designed to operate at a voltage range of 4.5V to 5.5V. This integrated circuit is part of the 74HCT family, which means it is compatible with TTL levels and has the ability to drive 15 LSTTL loads. The 74HCT253D is crafted for multiplexing and demultiplexing digital or analog signals, making it an ideal choice for a wide array of applications in the telecommunications, computing, and consumer electronics sectors.

Enclosed in a slim SOIC-16 package, the 74HCT253D features two individual 4-channel multiplexers with common select inputs and separate enable inputs. Each multiplexer has four inputs, one output, and two select inputs, which are used to choose one of the four inputs to be routed to the output. The 3-state outputs ensure that the device can be connected to a bus-organized system without the risk of bus contention, as the output can be effectively disconnected.

The device is characterized by its high noise immunity and low power consumption, which is typical for the HCT family. The 74HCT253D is also known for its high-speed performance, with a typical propagation delay of only 16ns, ensuring swift and reliable switching between channels, which is critical in high-speed digital systems.

Key features of the 74HCT253D include:

• Dual 4-channel multiplexing capability
• 3-state outputs for bus interfacing
