| DM74S140 Dual 4-Input NAND 50 Line Driver August 1986 Revised April 2000 DM74S140 Dual 4-Input NAND 50 Line Driver General Description This device contains two independent line driver gates each of which performs the logic NAND function. Ordering Code: Order Number DM74S140 Package Number N14A Package Description 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Connection Diagram Function Table Y = ABCD Inputs A X X X L H B X X L X H C X L X X H D L X X X H Output Y H H H H L H = HIGH Logic Level L = LOW Logic Level X = Either LOW or HIGH Logic Level (c) 2000 Fairchild Semiconductor Corporation DS006467 www.fairchildsemi.com DM74S140 Absolute Maximum Ratings(Note 1) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 5.5V 0C to +70C -65C to +150C Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation.
