Frequently Asked Questions
What type of latch is the CD54HCT75F3A?
The CD54HCT75F3A is a quad transparent D-type latch. When the enable input is high, the Q output follows the D input transparently in real time. When the enable is driven low, the output is latched and retains the last data state, providing a simple single-bit storage element for bus buffering and register applications.
What logic family does the CD54HCT75F3A belong to?
The CD54HCT75F3A belongs to the HCT (High-speed CMOS with TTL-compatible inputs) logic family. HCT devices operate from a 5V supply and use TTL-level input switching thresholds, making them directly interoperable with standard 74LS and 74S TTL-family logic without any level-translation circuitry.
Why is the CD54HCT75F3A in a ceramic DIP package?
The CD54HCT75F3A uses a ceramic 16-pin CDIP package (JESD-30 code R-GDIP-T16), which provides hermetic sealing that protects the die from moisture, corrosive atmospheres, and extreme temperature conditions. Ceramic packages are specified for military and high-reliability applications where plastic packages may fail under prolonged exposure to harsh environmental conditions.
What is the maximum operating frequency of the CD54HCT75F3A?
The CD54HCT75F3A supports a maximum operating frequency of 25MHz at nominal supply voltage. This frequency rating applies to the latch enable toggling rate and associated data transitions, making it suitable for use in digital systems with clock and bus frequencies up to this limit without timing violations.
Is the CD54HCT75F3A RoHS compliant?
The CD54HCT75F3A has JESD-609 code e0, which indicates that it is Pb-free (lead-free). However, the REACH compliance code is listed as Not Compliant, meaning it may contain certain restricted substances under REACH regulations. Designers targeting RoHS-only markets should verify the current compliance status with the distributor or manufacturer before design-in.
