NXP 74HCT4514PW - 4-to-16 Line Decoder/Demultiplexer with Input Latches

The NXP 74HCT4514PW is a high-speed Si-gate CMOS device that is pin compatible with low power Schottky TTL (LSTTL). It is designed to decode four binary input lines to one of sixteen mutually exclusive outputs. This particular component is a vital piece in various digital systems where it is necessary to convert binary information into a format suitable for display or further processing.

The device features an input latch with a LE (latch enable) input, making it possible to store a 4-bit word. This word is then used to determine which one of the sixteen outputs will go high. In addition to the latch feature, this decoder/demultiplexer includes an active low enable input (E), which can be used to enable or disable the decoding function, allowing for flexible control within a digital circuit.

Encased in a TSSOP-24 (thin shrink small outline package), the 74HCT4514PW is designed for space-saving on printed circuit boards and is suitable for SMT (surface-mount technology) assembly processes. Its balanced propagation delays and output transition times contribute to its reliable and predictable performance in high-speed applications.

Key features of the NXP 74HCT4514PW include:

• Decodes a 4-bit address to one of sixteen active high outputs
• Input latching capability for address hold
• Active low enable input for easy expansion or gating
• Complies with JEDEC standard no. 7A
• ESD protection: HBM JESD22-A114E exceeds 2000 V, MM JESD22-A115-A exceeds 200 V
• Multiple package options for design flexibility
• Specified from -40°C to +85°C and -40°C to +125°C

The 74HCT4514PW is suitable for a wide array of applications including computer systems, instrumentation, control systems, and anywhere a high-density, high-speed decoder is required. Its ability to interface with TTL logic levels also makes it versatile for mixed-technology environments.

Overall, the NXP 74HCT4514PW is a robust and reliable choice for designers looking to implement efficient decoding solutions in their digital systems, with the added advantage of latch control for more complex operations.
