TC7MB3245FK

TC7MB3245FT/FK Toshiba CMOS Digital Integrated Circuit Silicon Monolithic TC7MB3245FT, TC7MB3245FK Octal Bus Switch The TC7MB3245 provides eight bits of high-speed TTL-compatible bus switching in a standard ’245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as one 8-bit switch. When output enable ( OE ) is low, the switch is on and port A is connected to port B. When OE is high, the switch is open and a high-impedance state exists between the two ports. 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: TSSOP20,VSSOP20 (US20) Pin compatible with the 74xx245 type. Functionally equivalent to (FST/CBT) 3245. Pin Assignment (top view) TC7MB3245FT TC7MB3245FK Weight TSSOP20-P-0044-0.65A VSSOP20-P-0030-0.50 : 0.08 g (typ.) : 0.03 g (typ.)
