TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC7MBL3245SFT, TC7MBL3245SFK, TC7MBL3245SFTG

Low Voltage/Low Capacitance Octal Bus Switch

The TC7MBL3245S 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

• ESD performance: Machine model ≥ ±200 V

Human body model

≥ ±2000 V

• Power down protection for inputs ( OE input only)

• Package: TSSOP20,VSSOP (US20) , VQON20

• Pin compatible with the 74xx245 type

Note: When mounting VQON package, the type of recommended flux

is RA or RMA.
