That 24:1 ratio means the low side can drive a standard TTL fan-out of ten loads, but the high side is weak — you cannot directly drive an LED or a relay coil from the high output without a pull-up or a buffer. If the downstream input is CMOS with a high-impedance gate, the 1 mA source is fine; if it is a bipolar TTL input, plan on a pull-up resistor to hold the logic high level within VOH specs. ## Through-hole DIP — field-service friendly The 16-DIP package (0.300\" body width) is socket-friendly. On a repair call, you can swap this part with a standard IC extractor — no desoldering station, no hot air. If the board uses a machined-pin socket, the 7.62 mm row spacing matches standard 0.3\" DIP sockets. No need to worry about bent leads if you use a zero-insertion-force socket for programming or testing.","metaTitle":"SN74F151BN 74F 1x8:1 Multiplexer, 16-DIP, 4.5-5.5V","metaDescription":"SN74F151BN active 1 x 8:1 multiplexer from TI's 74F series.

The SN74F151BN is a bipolar 74F part: faster propagation delay (around 5 ns typical vs 15 ns for HC), but draws more supply current (around 10 mA quiescent vs microamps for HC). The F version is the pick for speed-critical 5 V buses; the HC version suits battery-powered or mixed-voltage designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74F151BN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74F151BN when reusing this data.
