TC74ACT157P/F/FN/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT157P,TC74ACT157F,TC74ACT157FN,TC74ACT157FT Quad 2-Channel Multiplexer Note: xxxFN (JEDEC SOP) is not available in Japan. The TC74ACT157 is an advanced high speed CMOS QUAD TC74ACT157P 2-CHANNEL MULTIPLEXER fabricated with silicon gate and 2 double-layer metal wiring C MOS 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 levles. This device consist of four 2-input digital multiplexer with common select and strobe inputs. TC74ACT157F When the ST input is held H level, selection of data is inhibited and all the outputs become L level. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: t = 5.1 ns (typ.) at V = 5 V pd CC TC74ACT157FN Low power dissipation: I = 8 A (max) at Ta = 25C CC Compatible with TTL outputs: V = 0.8 V (max) IL V = 2.0 V (min) IH Symmetrical output impedance: I = I = 24 mA (min) OH OL Capability of driving 50 transmission lines.
