TC7MZ245FK
Low Voltage Octal Bus Transceiver with 5 V Tolerant Inputs and Outputs
The TC7MZ245FK is a high performance CMOS octal bus
transceiver. Designed for use in 3.3 V systems, it achieves high
speed operation while maintaining the CMOS low power
dissipation.
The device is designed for low-voltage (3.3 V) V_CC applications,
but it could be used to interface to 5 V supply environment for
both inputs and outputs.
The direction of data transmission is determined by the level of
the DIR input. The enable input ( OE ) can be used to disable the
device so that the busses are effectively isolated.
All inputs are equipped with protection circuits against static
discharge.
Weight: 0.03 g (typ.)
Features
• Low voltage operation: V_CC = 2.0~3.6 V
• High speed operation: t_pd = 7.0 ns (max) (V_CC = 3.0~3.6 V)
• Output current: |I_OH|/I_OL = 24 mA (min) (V_CC = 3.0 V)
• Latch-up performance: −500 mA
• Package: VSSOP (US20)
• Bidirectional interface between 3.3 V and 5.0 V signals.
• Power down protection is provided on all inputs and outputs.
• Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 245 type.
Note: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.
All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull down
resistors.
