The Texas Instruments SN74LVT244BPW is a 2-element, 4-bit-per-element non-inverting buffer with 3-state outputs in a 20-TSSOP package. The asymmetric drive — twice the sink as source — is characteristic of the 74LVT family and matches the typical fan-out of a 3.3 V backplane or memory interface.
The 20-TSSOP body (4.40 mm wide,) fits dense PCB layouts where a wider SOIC would consume extra board area.
Yes, the SN74LVT244BPW is the 20-TSSOP variant of the standard 74LVT244 octal buffer. The 'B' suffix indicates TI's second-generation 74LVT process with improved drive and ESD performance. Function and pinout are identical to the generic 74LVT244 in a TSSOP package.
