Octal Low Voltage Bus Switch
The TC7MBL3245A provides eight bits of low-voltage, high-speed bus switching in a standard ’245 device pinout. The low ON-resistance of the switch allows connections to be made with minimal propagation delay and while maintaining CMOS low power dissipation.
The device comprises a single 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 to guard against static discharge.
Features
Operating voltage: VCC = 2.0 to 3.6 V High speed: tpd = 0.31 ns (max) @ VCC = 3.0 V Low ON-resistance: RON = 5 Ω (typ.) @ VCC = 3.0 V ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V Power-down protection for inputs ( OE input only) Package: TSSOP20,VSSOP20 (US20) Pin compatible with the 74xx245 type
