TOSHIBA 3-TO-8 LINE DECODER TC74HCT138AP/AF/AFN TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TC74HCT138AP, TC74HCT138AF, TC74HCT138AFN (Note) The JEDEC SOP (FN) is not available in Japan. The TC74HCT188A is a high speed CMOS 3-to-8 LINE DECODER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. When the device is enabled, 3 Binary Select inputs (A, B and C) determine which one of the outputs (YO - Y7) will go low. When enable input G1 is held low or either G2A or G2B is held high, decoding function is inhibited and all outputs go high. G1, G2A, and G2B inputs are provided to ease cascade connection and for use as an address decoder for memory systems, All inputs are equipped with protection circuits against static discharge or transient excess voltage. eee 16 Mai yi P (DIP 16-P-300-2.54A) Weight : 1.00g (Typ.) 1 1 F (SOP16-P-300-1.27) FN (SOL16-P-150-1.27) Weight : 0.189 (Typ.) = Weight : 0.13g (Typ.)
