74LVT2244DB中文资料3.3V Octal buffer/line driver with 30Ohm series termination resistors (3-State)数据手册Nexperia规格书

描述 Description

The LVT2244 is a high-performance BiCMOS product designed for VCC operation at 3.3 V.
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.
The 74LVT2244 is designed with 30 Ω series resistance in both the High and Low states of the output. This design reduces the line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters.

特性 Features

• Octal bus interface
• 3-State buffers
• Output capability: ±12 mA
• TTL input and output switching levels
• Input and output interface capability to systems at 5 V supply
• Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
• Power-up 3-State
• Live insertion/extraction permitted
• No bus current loading when output is tied to 5 V bus
• Latch-up protection exceeds 500 mA per JEDEC Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model
• Outputs include series resistance of 30 Ω, making external termination resistors unnecessary
