Frequently Asked Questions
What is the maximum clock frequency supported by the SN74ALS112ANSRE4?
The SN74ALS112ANSRE4 supports a maximum clock frequency of 30 MHz, making it suitable for moderate-speed sequential logic designs such as binary counters, frequency dividers, and synchronous state machines in the ALS logic family.
How does the SN74ALS112ANSRE4 differ from standard 74LS112 flip-flops in terms of output drive capability?
The SN74ALS112ANSRE4 provides a maximum output sink current (I_ol) of 8 mA, which is lower than the 74LS112's 16 mA. This reflects the ALS family's reduced power consumption trade-off, suitable for CMOS-dominant designs where lower drive current is acceptable.
Is the SN74ALS112ANSRE4 suitable for new RoHS-compliant designs shipping to the EU?
Yes, the SN74ALS112ANSRE4 carries a Pb-free / RoHS-compliant designation (JESD-609 code e4), meeting EU RoHS Directive requirements. Its SOP-16 package with standard 1.27 mm pitch is compatible with modern SMT assembly processes used in consumer and industrial product lines.
Which logic applications benefit most from using 2-bit J-K flip-flops like the SN74ALS112ANSRE4?
Applications such as 2-bit binary counters, toggle flip-flop chains operating at up to 30 MHz, and synchronous register designs benefit from this dual J-K configuration. Industrial control panels, PLC I/O modules, and digital instrumentation requiring edge-triggered latching at 5 V are typical use cases.
