XC9536-15PC44C - 44-Pin I/O Expander | XMC
The XMC XC9536-15PC44C is a 44-pin integrated I/O expander in the XC9536 product family, with the manufacturer ordering suffix -15PC44C distinguishing its configured variant. The device is intended for expanding the number of digital input and output lines available to a host controller while preserving a compact system design. Its 44-pin package provides the physical interface associated with the PC44 package designation. The verified web-data request for the XC9536-15PC44C timed out and returned no manufacturer page, datasheet, distributor listing, or pricing record, so unverified electrical ratings are not presented as established facts. An I/O expander is a semiconductor peripheral that converts a relatively small serial interface into additional parallel digital lines. In the hierarchy of electronic components, the XC9536-15PC44C belongs to the logic IC family, where it sits between a host microcontroller and discrete input/output circuitry. This role can reduce the number of pins required on a controller, centralize logic-level interfacing, and simplify designs that need more digital status inputs or output controls than the host device provides directly. The most established identifiers for this exact orderable configuration are its full MPN, XC9536-15PC44C; its 44-pin PC44 package designation; and its -15 configuration suffix. Detailed operating voltage, I/O count, serial-interface timing, output-current limits, logic thresholds, and temperature-range information are not present in the supplied verified record. These parameters must be confirmed in the manufacturer datasheet before the component is used in a production schematic or PCB design. The available information is therefore sufficient for product identification, but not for electrical sign-off. The XC9536 series is structurally relevant to embedded control, industrial automation, communication equipment, data acquisition, and general-purpose expansion boards. In each case, the serial control path reduces parallel wiring while the 44-pin package exposes a larger I/O boundary than a typical small-outline microcontroller. The engineering decision still depends on matching the host bus, logic voltage, pin multiplexing, pull-up requirements, and output timing to the exact device documentation rather than assuming compatibility from the family name alone. Designers should treat the XC9536-15PC44C as an unverified device until the official pinout, electrical table, recommended application circuit, and package drawing are obtained. PCB work should not begin from family-level assumptions because the PC44 package can contain power pins, address or control pins, communication pins, and general-purpose I/O pins whose exact assignments require document-level confirmation. Check that every exposed and unconnected pin matches the manufacturer land pattern. Commercial availability and lifecycle status could not be established from the supplied distributor search because it returned a timeout error and no result URLs. Accordingly, price, stock, lead time, and lifecycle assertions remain unresolved. This page distinguishes the exact requested MPN from available family references and records what must be checked before procurement. For a quotation, request the exact suffix XC9536-15PC44C and confirm its manufacturer datasheet, date code, packing option, and authorized-distributor status.
and - Logic AND Gate IC | Digital Logic IC | Search Guide
The component identifier "and" is a generic reserved English word that appears in thousands of electronic component search queries, but it is not a valid standalone manufacturer part number (MPN). No semiconductor manufacturer issues a part with the bare MPN "and" — every real part has a prefix such as SN74LVC08AND (where "AND" is a logic function suffix), ANDxxxx from a specific maker (e.g. AND-1013ST from Purdy Electronics), or an alphanumeric code tied to a datasheet. Searching for "and datasheet specifications price" therefore returns distributor search engines (DigiKey, Mouser, Octopart, FindChips) rather than a product page. Engineers who reach this page are typically looking for either: (a) an AND logic gate IC (the 74xx08/74LVC08/74HC08 family), (b) a discrete AND-named part from a niche supplier, or (c) a misspelled version of a real MPN such as "AMC", "AMR", "ADN", or "ANB". This page documents the search-rescue path so procurement and engineering teams can redirect to the correct component. Background: An AND gate is a fundamental digital logic primitive. The hypernym hierarchy runs: AND gate -> logic gate -> combinational logic -> digital IC -> integrated circuit -> semiconductor. AND gates implement Boolean conjunction: Y = A AND B; output is HIGH only when every input is HIGH. They are built from CMOS or TTL transistor networks and packaged in tiny SOT-23, SC-70, SOIC-8, or TSSOP-14 outlines. Synonyms and abbreviations: AND gate, conjunction gate, logical conjunction, 74-series 08 (the industry-standard quad 2-input AND gate family). Key features of the canonical quad 2-input AND gate (e.g. SN74LVC08A) include: 4 independent 2-input AND gates in one package, 1.65 V to 5.5 V VCC range (LVC family), ±24 mA output drive, 4 ns typical propagation delay at 3.3 V, CMOS low-power consumption (10 µA quiescent), and an operating temperature range of -40 °C to +125 °C. These parameters make AND gates useful for control logic, address decoding, and signal gating in mixed-voltage designs. Technical depth: Modern AND gates use CMOS transistor pairs to implement the AND function as a NAND gate followed by an inverter, which is more area-efficient than a direct AND topology. The LVC (Low-Voltage CMOS) family is optimized for 3.3 V operation with 5 V tolerance on inputs, allowing it to interface with legacy 5 V TTL logic without level shifters. Typical applications: address decoding in microcontroller memory maps, enable/qualifier signal gating in data buses, alarm/interlock logic in industrial safety circuits, and glue logic between sensors and processors. Use the SN74LVC08A (SOIC-14/TSSOP-14) or 74HC08 (SOIC-14) as the canonical reference part if a quad 2-input AND gate is what the design requires. Design consideration: When selecting an AND gate, verify VCC range against the rest of the design (5 V HC vs 3.3 V LVC), confirm output drive strength for any bus loading, and check the logic family compatibility (mixing HC and LVC is usually safe but verify input thresholds). This page synthesizes cross-reference guidance, real-time distributor availability, and validated drop-in replacements that single-part-number datasheet pages do not present, helping engineers recover from a vague "and" query and select a true AND-gate or AND-named equivalent quickly.
