Frequently Asked Questions
What is the output current capability of the SN74ALS253N?
The SN74ALS253N supports a maximum output sink current (I_OL) of 24mA, making it compatible with standard TTL and LSTTL loads. This ensures reliable signal driving across typical digital logic applications without the need for additional buffers.
Can the SN74ALS253N outputs be connected directly to a shared data bus?
Yes. The SN74ALS253N features 3-state (tri-state) outputs, which allow multiple devices to share a common bus line. When disabled, the outputs enter a high-impedance state, preventing bus contention and enabling clean multiplexed data transfer in microprocessor and memory systems.
What package does the SN74ALS253N use and what are typical applications?
The SN74ALS253N comes in a standard 16-pin DIP (Dual-In-Line Package), which is suitable for through-hole PCB assembly. Typical applications include address/data bus multiplexing, memory bank selection, signal routing in embedded systems, industrial controllers, and communications equipment.
Is the SN74ALS253N RoHS compliant?
Yes, the SN74ALS253N carries a Pbfree code of 'Yes' and a JESD-609 code of e4, indicating it is manufactured without lead and complies with RoHS environmental regulations, making it suitable for use in modern eco-friendly electronic designs.
