1 / 6 page TC7MB3244FK 2007-10-19 1 Toshiba CMOS Digital Integrated Circuit Silicon Monolithic TC7MB3244FK Octal Bus Switch The TC7MB3244FK provides eight bits of high-speed TTL-compatible bus switching in a standard ’244 device pinout. The low on resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as two 4-bit low-impedance switches with separate output-enable (OE) inputs. When OE is low, the switch is on and data can flow from port A to port B, or vice versa. 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 Pin Assignment (top view) • Operating voltage: VCC = 4.5~5.5 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: VSSOP (US20) • Pin compatible with the 74xx244 type. Functionally equivalent to (FST/CBT) 3244. Weight: 0.03 g (typ.) VCC 20 OE 2 1B1 2A4 19 18 17 OE 1 1 2 3 4 1A2 1A1 2B4 1B2 16 2A3 1B3 2A2 15 14 13 2B3 5 6 7 8 1A4 1A3 2B2 1B4 2A1 12 11 9 10 GND 2B1 |
