SN54LVTH16244A, SN74LVTH16244A are 3.3-V ABT 16-bit buffers/drivers with 3-state outputs, members of the Texas Instruments Widebus™ family.
The SN54LVTH16244A and SN74LVTH16244A devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) Vcc operation with the capability to provide a TTL interface to a 5-V system environment. These devices can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
| Operating Temperature (Commercial) | -40°C to 85°C |
|---|---|
| High-Level Output Current | 32 mA (SN74LVTH16244A) |
| Low-Level Output Current | 64 mA (SN74LVTH16244A) |
The devices are designed for low-voltage (3.3-V) Vcc operation, with a recommended operating range of 2.7 V to 3.8 V.
Yes, they support mixed-mode signal operation with 5-V input and output voltages while operating at a 3.3-V Vcc.
No, active bus-hold circuitry eliminates the need for external pullup/pulldown resistors.
