Product data sheet
1 General description
The 74LVT244B; 74LVTH244B 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 enable inputs (1OE and 2OE), each controlling four of the 3-state outputs.
2 Features and benefits
Octal bus interface
3-state buffers
Speed upgrade of 74LVT244A
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
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: exceeds 500 mA
ESD protection:
HBM EIA/JESD22-A114-C exceeds 2000 V
MM EIA/JESD22-A115-A 200 V
