74LVT244B
FEATURES
- Octal bus interface
- 3-State buffers
- Speed upgrade of 74LVTH244A
- Output capability: +64m A/-32m A
- TTL input and output switching levels
- Input and output interface capability to systems at 5V supply
- Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
DESCRIPTION
The LVT244B is a high-performance Bi CMOS product designed for VCC operation at 3.3V. This device is an octal buffer that is ideal for driving bus lines. The device features two Output Enables (OE1, OE2), each controlling four of the 3-State outputs.
- Power-up 3-State
- Live insertion/extraction permitted
- No bus current loading when output is tied to 5V bus
- Latch-up protection exceeds 500m A per JEDEC Std 17
- ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model
