ON Semiconductor MM74HC4514MTCX: A High-Performance Decoder

The MM74HC4514MTCX is a versatile and high-performance 4-to-16 line decoder/demultiplexer fabricated by ON Semiconductor. This integrated circuit is designed to provide ease of use and flexibility in a wide range of applications, including but not limited to, data multiplexing, signal decoding, and memory address decoding.

This decoder is part of the advanced high-speed CMOS (HC) family and is recognized for its robustness and low power consumption. It operates with a supply voltage ranging from 2V to 6V, making it suitable for battery-operated devices and low-voltage applications. The MM74HC4514MTCX is also characterized by its high noise immunity and the ability to drive 10 LS-TTL loads, ensuring reliable performance in complex electronic systems.

The MM74HC4514MTCX features a 4-bit input structure, which allows it to decode 16 different output lines. Each output can sink 25mA, providing the capability to drive LEDs, relays, or other visual indicators directly. The device includes an input latch, a 4-to-16 line decoder, an output latch, and a 4-bit address latch with strobe. The strobe (ST) input must be at a high logic level to enable the device, while the enable (E) input, when low, disables the decoder and forces all outputs to a high impedance state, thus reducing power consumption.

The package is a 24-pin TSSOP, offering a compact footprint for space-constrained applications. It is also lead-free and RoHS compliant, ensuring environmental sustainability and meeting global regulatory requirements for electronic components.

With its fast propagation delay times and low quiescent current, the MM74HC4514MTCX is an ideal choice for high-speed memory decoders, microprocessor peripheral interfaces, and other digital logic applications where efficient decoding is required. Its robust design and ON Semiconductor's commitment to quality make it a reliable component for both commercial and industrial electronic systems.
