TC74VHCT138AFK

TC74VHCT138AF/AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT138AF, TC74VHCT138AFK 3-to-8 Line Decoder TC74VHCT138AF The TC74VHCT138 is an advanced high speed CMOS 3-to-8 LINE DECODER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. When the device is enabled, 3 Binary Select inputs (A, B and C) determine which one of the outputs ( Y0 to 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. The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. Note: VCC = 0 V Features TC74VHCT138AFK Weight SOP16-P-300-1.27A VSSOP16-P-0030-0.50  High speed: tpd = 7.6 ns (typ.) at VCC = 5 V  Low power dissipation: ICC = 4 μA (max) at Ta = 25°C  Compatible with TTL inputs: VIL = 0.8 V (max) VIH = 2.0 V (min)  Power down protection is provided on all inputs a...
