SN54ALS32, SN54AS32, SN74ALS32, SN74AS32 QUADRUPLE 2-INPUT POSITIVE-OR GATES SDAS113B. This document is about the datasheet of SN54ALS32, SN54AS32, SN74ALS32, SN74AS32 4-channel 2-input positive OR gates
The SN54ALS32, SN54AS32, SN74ALS32, and SN74AS32 devices each contain four independent 2‑input positive‑OR gates that implement the Boolean function Y = A + B in positive logic. The SN54 series are qualified for the full military temperature range (‑55 °C to 125 °C) while the SN74 series are specified for commercial temperature ranges (0 °C to 70 °C).
These parts are offered in multiple package styles, including Plastic Small‑Outline (SO), Ceramic Chip‑Carrier (FK), and standard Plastic (N) and Ceramic (J) DIP packages. Key electrical parameters include a supply voltage of 4.5 V to 5.5 V, VIH of 2 V, VIL of 0.8 V, and output currents of –0.4 mA (high) to 8 mA (low).
