Frequently Asked Questions
What is the primary difference between the 74HC/HCT237 and a standard decoder?
It combines the 3-to-8 decoder function with a 3-bit latch, allowing captured addressing via the LE pin.
How does the device store or capture an address using its latching capability?
When the latch enable (LE) goes from LOW to HIGH, the last input address is stored in the output latches and subsequent changes are ignored as long as LE remains high.
Are these devices compatible with various TTL logic standards?
Yes, they are pin compatible with low power Schottky TTL (LSTTL) and specified in compliance with JEDEC standards.
What inputs control the outputs independently of the address pins or latching?
The data enable input ($ ext{E}$) and the $ ext{EE}$ input control the state of the outputs. Outputs are HIGH unless E is LOW and EE is HIGH.
