TC74ACT138F

TC74ACT138P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT138P, TC74ACT138F, TC74ACT138FT 3-to-8 Line Decoder The TC74ACT138 is an advanced high speed CMOS 3-to-8 LINE DECODER fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL 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 ( Y0 - 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. Features High speed: tpd = 6.0 ns (typ.) at VCC = 5 V Low power dissipation: ICC = 8 μA (max) at Ta = 25°C Compatible with TTL outputs: VIL = 0.8 V (max) VIH = 2.0 V (min) Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Pin and function compatible with 74F138 TC74ACT138P TC74ACT138F TC74ACT138FT Weight DIP16-P-300-2.54A SOP16-P-300-1.27A TS...
