TC7MA245FK
Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs
The TC7MA245FK is a high performance CMOS octal bus
transceiver. Designed for use in 1.8 , 2.5 or 3.3 V systems, it
achieves high speed operation while maintaining the CMOS low
power dissipation.
It is also designed with over voltage tolerant inputs and
outputs up to 3.6 V.
The direction of data transmission is determined by the level of
the DIR inputs. The OE inputs can be used to disable the device
so that the busses are effectively isolated.
All inputs are equipped with protection circuits against static
discharge.
Features
• Low voltage operation: VCC = 1.8~3.6 V
• High speed operation:
tpd = 3.5 ns (max) (VCC = 3.0~3.6 V)
tpd = 4.2 ns (max) (VCC = 2.3~2.7 V)
tpd = 8.4 ns (max) (VCC = 1.8 V)
• 3.6 V tolerant inputs and outputs.
• Package: VSSOP (US20)
• Output current:
IOH/IOL = ±24 mA (min) (VCC = 3.0 V)
IOH/IOL = ±18 mA (min) (VCC = 2.3 V)
IOH/IOL = ±6 mA (min) (VCC = 1.8 V)
• Latch-up performance: ±300 mA
• ESD performance:
Machine model > ±200 V
• Human body model > ±2000 V
• Bidirectional interface between 2.5 V and 3.3 V signals. (*1)
• Power down protection is provided on all inputs and outputs. (*2)
• Supports live insertion/withdrawal (*3)
Weight: 0.03 g (typ.)
*1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.
*2: All floating (high impedance) bus terminal must have their input level fixed by means of pull up or pull down
resistors.
*3: To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a
pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
