74ABT245CSJ Equivalent & Substitute Parts
Part Overview
The 74ABT245CSJ is a non-inverting transceiver logic IC manufactured by onsemi, featuring 1 element with 8 bits per element and 3-state output capability. Designed for 4.5V to 5.5V supply operation with 20-SOP packaging, this component is classified as obsolete product status. Due to its obsolete designation, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure long-term component availability for new production and legacy system support.

Substitute Part Grouping Explanation
Substitution of the 74ABT245CSJ is determined by strict equivalence across the following critical parameters: logic type (non-inverting transceiver), number of elements (1), bits per element (8), output type (3-state), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and mounting type (surface mount). Package variations between 20-SOIC (0.295", 7.50mm width) and 20-SOP/20-SO (0.209", 5.30mm width) are acceptable substitutions provided PCB layout accommodates the physical dimensions. Output current specifications (32mA high, 64mA low) remain consistent across all qualified substitutes. All substitute parts listed maintain identical functional performance and electrical characteristics required for direct replacement in circuit applications.

SN74ABT2245DW is functionally equivalent with identical logic type, element count, bit width, output type, supply voltage, temperature range, and output current specifications. The primary difference is package width (0.295" vs 0.209"), which requires PCB layout verification.
Q: What is the difference between 20-SOIC and 20-SO packages? A: Both are surface-mount packages with 20 pins. The primary distinction is physical width: 20-SOIC (0.295", 7.50mm) and 20-SO/20-SOIC (0.209", 5.30mm). Electrical performance is identical; selection depends on available PCB footprint space.
Q: Are 74ABT and 74ABTH series interchangeable? A: Yes. Both series maintain identical electrical specifications for voltage supply, operating temperature, output current, and logic function. The ABTH designation indicates a variant within the same functional family with equivalent performance characteristics.
Q: What packaging options are available for substitutes? A: Substitute parts are available in Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel packaging. Selection depends on production volume and assembly process requirements.
Q: Are all substitutes RoHS3 compliant? A: Yes. All Texas Instruments substitute parts listed are ROHS3 compliant, meeting environmental and regulatory requirements for modern manufacturing.
Q: Does package width affect electrical performance? A: No. Package width variations (0.209" vs 0.295") do not affect electrical performance. Selection is based solely on PCB layout compatibility and available footprint space.
Q: Can I use SN74ABT623NS as a substitute? A: Yes. SN74ABT623NS is a parametric equivalent with identical logic type, element count, bit width, output type, supply voltage, temperature range, and output current specifications. Package dimensions are 20-SO (0.209", 5.30mm width).
