74LVT2245; 74LVTH2245
General description
The 74LVT2245; 74LVTH2245 is a high-performance BiCMOS product designed for VCC operation at 3.3 V.
This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable input (OE)for easy cascading and a direction input (DIR) for direction control.
The 74LVT2245; 74LVTH2245 is designed with 30 Ohm series resistance in both the HIGH-state and LOW-state of the output. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceivers and transmitters.
Features
- 30 Ohm output termination resistors
- Octal bidirectional bus interface
- 3-state buffers
- Output capability: +12 mA and -12 mA
- TTL input and output switching levels
- Input and output interface capability to systems at 5 V supply
- Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
- Live insertion and extraction permitted
- Power-up 3-state
- No bus current loading when output is tied to 5 V bus
- Latch-up protection:
- JESD78: exceeds 500 mA
- ESD protection:
- MIL STD 883 method 3015: exceeds 2000 V
- Machine model: exceeds 200 V
