TC74ACT139FT

TC74ACT139P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT139P, TC74ACT139F, TC74ACT139FT Dual 2-to-4 Line Decoder The TC74ACT139 is an advanced high speed CMOS 2 to 4 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. The active low enable input can be used for gating or it can be used as a data input for demultiplexing applications. When the enable input is held “H”, all four outputs are fixed at a high logic level independent of the other inputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: tpd = 5.5 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 74F139 TC74ACT139P TC74ACT139F TC74ACT139FT Weight DIP16-P-300-2.54A SOP16-P-300-1.27A TSSOP16-P-0044-0.65A : 1.00 g (typ.) : 0.18 g (typ.) : 0.06 g (typ.)
