The Texas Instruments SN74LVT244BDB is a 74LVT-series non-inverting buffer with 3-state outputs, organized as two 4-bit elements.
If your bus runs at 3.3 V nominal with ±10 % tolerance, the SN74LVT244BDB stays within its rated range even during a 3.0 V brown-out. The 32 mA source / 64 mA sink capability is enough to drive a terminated backplane or a bank of LED indicators without external transistors, but check the total package dissipation if all eight outputs are loaded simultaneously at full current.
The SN74LVT244BDB is housed in a 20-SSOP package with a 5.30 mm body width.
No EOL notice or successor part is recorded for this order code.
