The headline number here is the asymmetric output drive: 32 mA source on the high side and 64 mA sink on the low side, which gives you enough current to drive a heavily loaded backplane or a bank of LED indicators without external line drivers. ## Rework on a 20-TSSOP — pin 1 is where you expect it The 20-TSSOP body is 4.40 mm wide with a 0.65 mm pitch — tight enough that a standard chisel tip needs steady hands, but doable with hot air at 300°C and a gentle nudge. The orientation mark is on the top-left corner looking down, pin 1 index at the chamfer. No exposed pad underneath, so you don't have to worry about a hidden thermal slug; just tack the corner pins first, flow the rest with a fine iron, and inspect under a scope. It's a surface-mount part that survives a rework cycle cleanly if you keep the dwell time under 10 seconds per side. ## Industrial temperature rating and active lifecycle RoHS3 compliant per the compliance listing. The 20-TSSOP footprint is common enough that board layout is straightforward.","metaTitle":"SN74ABT241APW Buffer, Non-Inverting, 3-State, 20-TSSOP, 5.5V","metaDescription":"Texas Instruments SN74ABT241APW dual 4-bit buffer with 3-state outputs. 32mA/64mA drive, 4.5V-5.5V supply, -40°C to 85°C. 20-TSSOP package.

For a direct pin-compatible replacement, check the TI 74ABT series octal buffers; the SN74ABT241 is the specific dual 4-bit variant."},{"question":"How does SN74ABT241APW compare to SN74ABT240?","answer":"The SN74ABT240 is an inverting octal buffer/line driver, while the SN74ABT241APW is a non-inverting dual 4-bit buffer. If your design needs inverted outputs, the 240 is the choice; for non-inverted, the 241 fits.
