The XD74LS93 from Xinluda (XINLUDA) is a 4-bit binary ripple counter belonging to the popular 74LS93 / 7493 LS-TTL logic family. Internally it consists of four master-slave flip-flops arranged as a divide-by-two section and a separate divide-by-eight section, each with its own clock input. By externally connecting the Q0 output of the divide-by-two section to the divide-by-eight clock input, the device functions as a single 4-bit binary (divide-by-16) ripple counter, with simultaneous frequency divisions of 2, 4, 8 and 16 available at outputs Q0 through Q3.
State changes are initiated on the high-to-low (falling) transition of the clock inputs. A gated AND asynchronous master reset (MR1, MR2) overrides both clocks and resets all flip-flops to zero, making the part well suited to general-purpose frequency-division and counting tasks. The XD74LS93 is a drop-in functional equivalent to the industry-standard 74LS93 / SN74LS93 and is supplied by Xinluda in a through-hole DIP-14 package.
The XD74LS93 is a niche, Xinluda-branded logic part with little to no authorized-distributor stock, which makes it difficult to source through mainstream channels. Pacific Component Xchange specializes in hard-to-find and obsolete logic devices and power-management ICs, helping engineers and procurement teams secure components that are otherwise unavailable. We focus on authenticity and traceability, offer global shipping, and support both prototype and production volumes. If you need the XD74LS93 or a verified equivalent, request a quote (RFQ) from Pacific Component Xchange and our sourcing team will respond with current availability and lead time.
The XD74LS93 is Xinluda's version of the standard 74LS93 / 7493 4-bit binary ripple counter. It contains a divide-by-two section and a divide-by-eight section that can be combined to form a divide-by-16 binary counter.
Xinluda supplies the XD74LS93 in a through-hole DIP-14 (14-pin dual in-line) package, as listed in the XINLUDA XD74LS90/XD74LS93 counters datasheet.
Yes. The XD74LS93 is a functional equivalent of the industry-standard 74LS93 / SN74LS93 4-bit binary counter and follows the same pinout and operating behavior.
Connect the Q0 output of the divide-by-two section to the clock input of the divide-by-eight section and apply the input pulses to the first clock input. Outputs Q0 to Q3 then provide divisions of 2, 4, 8 and 16.
The XD74LS93 is manufactured by Xinluda (XINLUDA). Because authorized-distributor stock is limited, Pacific Component Xchange sources it on a request-for-quote (RFQ) basis with global shipping.
Yes, the XD74LS93 is available through Pacific Component Xchange. Submit an RFQ and our team will confirm current availability, lead time, and pricing.
