ElectronicsThe NTE74LS640 with INTEGRATED CIRCUIT LOW-POW is a custom integrated circuit designed and manufactured by NTE Electronics, Inc. It is a sixteen-bit register file suitable for use in logic and timing systems. The NTE74LS640 uses a low-power, high-speed CMOS technology, making it an ideal replacement for previously used TTL register files. The device utilizes four individual 16-bit addressable registers, accessible via pins A0-A15, B0-B15, C0-C15 and D0-D15. The NTE74LS640 is available in two versions: the 0.100-inch wide plated through-hole package suitable for applications requiring high shock and vibration resistance, and the 0.150-inch wide surface mount package for high reliability in automated assembly operations. Both packages are RoHS compliant. With its low-power, high-speed CMOS technology, the NTE74LS640 is ideal for a variety of logic and timing applications.
