74LVT240
3.3 V Octal inverting buffer/line driver; 3-state
Rev. 3 — 10 April 2017 Product data sheet
1 General description
The 74LVT240 is a high-performance BiCMOS product designed for V
CC
operation at
3.3 V.
This device is an octal inverting buffer that is ideal for driving bus lines. The device
features two output enable pins (1OE, 2OE), each controlling four of the 3-State outputs.
2 Features and benefits
• Octal bus interface
• 3-state buffers
• Output capability: +64 mA and -32 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 Class II exceeds 500 mA
• ESD protection:
– MIL STD 883 method 3015: exceeds 2000 V
