Frequently Asked Questions
What is the counting direction and maximum count range of the SN74AS869NT?
The SN74AS869NT supports bidirectional (up/down) synchronous binary counting over an 8-bit range (0 to 255). Direction is controlled by a dedicated input pin, allowing seamless switching between increment and decrement operations without losing count state.
What are the key features of the SN74AS869NT counter IC?
Key features include an 8-bit synchronous up/down count, TCO (Terminal Count Output) for cascading, count enable inputs, synchronous load/preset capability, and operation in the AS (Advanced Schottky) logic family with a 50 pF load capacitance. It uses a 24-pin PDIP package and is Pb-free (JESD-609 e4 compliant).
Can the SN74AS869NT be cascaded to build wider counters?
Yes. The TCO (Terminal Count Output) and count enable inputs are specifically designed to allow easy cascading of multiple SN74AS869NT devices to create 16-bit, 24-bit, or wider synchronous counters without additional glue logic.
What package does the SN74AS869NT come in and is it RoHS compliant?
The SN74AS869NT is housed in a 24-pin PDIP (R-PDIP-T24) small outline package. It is Pb-free with JESD-609 code e4, confirming RoHS compliance for lead-free manufacturing.
What is the price and availability of the SN74AS869NT?
The SN74AS869NT is priced from approximately $1.88 per unit and is available in stock with worldwide shipping, making it accessible for both prototyping and production requirements.
