TC74AC157F

TC74AC157P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC157P, TC74AC157F, TC74AC157FT Quad 2-Channel Multiplexer The TC74AC157 is an advanced high speed CMOS QUAD 2-CHANNEL MULTIPLEXER 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 consist of four 2-input digital multiplexer with common select and strobe inputs. When the STROBE 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: tpd = 4.5 ns (typ.) at VCC = 5 V Low power dissipation: ICC = 8 μA (max) at Ta = 25°C High noise immunity: VNIH = VNIL = 28% VCC (min) Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 5.5 V Pin and function compatible with 74F157 TC74AC157P TC74AC157F TC74AC157FT 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.)
