Each of the four buffers sinks 64 mA and sources 32 mA — enough headroom to drive a lightly loaded backplane or a bank of LED indicators without external line drivers. The 3-state outputs let multiple buffers share a common data line; the enable pin on each channel decides which one talks and which ones listen. ## Package and rework reality Housed in a 14-SOIC (0.209\", 5.30 mm body width) with a 1.27 mm pitch, this package reflows cleanly with a standard hot-air profile. The wide pin spacing makes visual inspection and hand rework straightforward — the part lifts without pad damage if the board is preheated to 100°C. Pin 1 is clearly marked by a chamfer on the package body, so orientation is unambiguous under a loupe. At the cold end, the 2.7 V minimum supply ensures the buffer still switches reliably when the 3.3 V rail droops under load. The 74LVTH series is a BiCMOS logic family that combines the speed of ABT with the low static power of CMOS. This buffer is a drop-in for legacy 74LVT or 74ABT sockets where the supply is 3.3 V, though the input thresholds are 5 V tolerant — a detail worth confirming against the driving device's output levels.","metaTitle":"SN74LVTH126NSR Buffer, Non-Inverting, 3.6V, 14-SOIC","metaDescription":"Texas Instruments SN74LVTH126NSR, 74LVTH series buffer with 3-state outputs. 2.7V–3.6V supply, 32/64mA drive, -40°C to 85°C.
