DM54132 - National Semiconductor

DM54132 DM54132/DM74132 Quad 2-Input NAND Gates with Schmitt Trigger Inputs

This device contains four independent gates each of which performs the logic NAND function Each input has hysteresis which increases the noise immunity and transforms a slowly changing input signal to a fast changing jitter-free output Connection Diagram Dual-In-Line Package TL F 6542 – 1 Order Number DM54132J or DM74132N See NS Package Number J14A or N14.
