TC7MB3257FK

TC7MB3257FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MB3257FT, TC7MB3257FK Quad 1-of-2 Multiplexer/Demultiplexer The TC7MB3257 is high-speed CMOS quad 1-2 multiplexer/demultiplexer. The low on resistance of the switch allows connections to be made with minimal propagation delay time. This device consists of four individual two-inputs multiplexer/demultiplexer with common select input (S) and output enable ( OE ). The A inputs is connected to the B1 or B2 outputs determined by the combination both the select input (S) and output enable ( OE ). When the output enable ( OE ) input is held “H” level, the switches are open with regardless the state of select inputs and a high-impedance state exists between the switches. All inputs are equipped with protection circuits against static discharge. Features Operating voltage: VCC = 4.5 to 5.5 V High speed: tpd = 0.25 ns (max) Low on resistance: RON = 5 Ω (typ.) ESD performance: Machine model ≥ ±200 V Human body model ≥ ±2000 V Compatible with TTL outputs (control inputs) Package: TSSOP16,VSSOP16 (US16) Pin compatible with the 74xx257 type. Functionally equivalent to (FST/CBT) 3257. Pin Assignment (top view) TC7MB3257FT TC7MB3257FK Weight: TSSOP16-P-0044-0.65A VSSOP16-P-0030-0.50 : 0.06 g (typ.) : 0.02 g (typ.)
