Product data sheet

1. General description

The 74LVT2244 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 (1OE, 2OE), each controlling four of the 3-state outputs.

The 74LVT2244 is designed with 30  series resistance in both the HIGH and LOW states

of the output. This design reduces line noise in applications such as memory address

drivers, clock drivers, and bus receivers/transmitters.

2. Features and benefits

 Octal 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

 Power-up 3-state

 Live insertion and extraction permitted

 No bus current loading when output is tied to 5 V bus

 Latch-up protection

 JESD78 Class II exceeds 500 mA

 ESD protection:

 HBM JESD22-A114E exceeds 2000 V

 MM JESD22-A115-A exceeds 200 V
