SN7437N

Quadruple 2-Input Positive-NAND Buffer integrated circuit, standard 14-pin plastic dual-in-line package footprint manufactured by Texas Instruments. Features high-drive internal transistor paths built to manage heavily loaded system logic branches with rapid propagation capabilities. Used to buffer system distribution lines, clock loops, and multi-gate hardware networks. Industry exact equivalents include Signetics N7437N, Fairchild DM7437N, Motorola MC7437N, and NTE7437. Historical equipment applications include the Bally Midway Pac-Man arcade board, Williams Defender cabinet, Seeburg SMC1 jukebox, Roland TR-808 drum machine, and Korg MS-20 synthesizer. [1]
