1 / 4 page SN74AS1804 HEX 2-INPUT NAND DRIVER SDAS042C – AUGUST 1984 – REVISED JANUARY 1995 Copyright © 1995, Texas Instruments Incorporated 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 • High Capacitive-Drive Capability • Typical Delay Time of 2.6 ns (C L = 50 pF) and Typical Power Dissipation of Less Than 9 mW Per Gate • Center V CC and GND Configuration Provides Minimum Lead Inductance in High-Current Switching Applications • Package Options Include Plastic Small-Outline (DW) Packages and Standard Plastic (N) 300-mil DIPs description This device contains six independent 2-input NAND drivers. It performs the Boolean functions Y = A • B or Y = A + B in positive logic. The center-pin configuration reduces lead inductance when compared to the ′AS804B. The reduced lead inductance minimizes noise generated onto either the VCC or GND bus. This reduction is significant in high-current switching applications. The SN74AS1804 is characterized for operation from 0 °C to 70°C.
