Product data sheet
1. General description
The 74LVT244A; 74LVTH244A 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.
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:
HBM JESD22-A114E exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
