What are the key features of CD54HC75F3A?

  • 4 independent D-type transparent latch channels operating up to 28 MHz for high-speed logic signal buffering
  • HC CMOS family with 2 V to 6 V supply compatibility and 50 pF load capacitance drive capability
  • 16-pin ceramic DIP package (CDIP) for high-reliability military and industrial applications requiring hermetic sealing

What is CD54HC75F3A used for?

The CD54HC75F3A is used in digital systems requiring temporary data storage and bus isolation, such as address latching on parallel microprocessor buses and data buffering in industrial programmable logic controllers. Its 4 transparent D-latch channels capture data on the low enable state, making it suitable for glitch-free data transfer across asynchronous clock domains in legacy military and aerospace hardware. The ceramic DIP package ensures long-term reliability in high-temperature storage and operation above the commercial temperature range.

Frequently Asked Questions

How many latch channels does the CD54HC75F3A provide, and at what maximum clock frequency can it operate?

The CD54HC75F3A provides 4 independent transparent D-type latch channels. It operates at a maximum frequency of 28 MHz at nominal supply voltage with a 50 pF load capacitance. This makes it suitable for address and data latching in parallel bus architectures used in embedded controllers, DSP systems, and legacy industrial logic designs that require deterministic data capture.

Why would a designer choose the ceramic DIP package of the CD54HC75F3A over a plastic SOIC version for aerospace use?

The CD54HC75F3A is supplied in a hermetically sealed ceramic DIP (CDIP) package, which provides superior moisture resistance and thermal stability compared to plastic SOIC packages. In aerospace and military applications operating above 85°C or exposed to humidity and contaminants, the ceramic package maintains electrical integrity over the full military temperature range of -55°C to +125°C, where plastic packages may degrade or fail over long mission lifetimes.

How does the enable input of the CD54HC75F3A control data transparency, and how does this differ from a flip-flop?

In the CD54HC75F3A, each D-type latch is transparent when the enable input is high, meaning the output follows the data input in real time. When enable goes low, the last data state is latched and held regardless of subsequent input changes. Unlike an edge-triggered flip-flop that samples only on a clock edge, the transparent latch passes data continuously during the enable-high period, which is useful for address demultiplexing on 8-bit and 16-bit parallel buses.
