It selects one of two 4-bit data sources based on a single select input, making it a straightforward choice for data routing in mixed-voltage systems. ## Supply voltage and output drive The 12mA output drive at both high and low levels is enough to fan out to a few CMOS loads or drive an LED indicator directly, but it is not a heavy bus driver — keep the total capacitive load under 50 pF if you want clean edges at 5V. ## Package and field-swap reality Housed in a 16-TSSOP (4.40 mm wide body), this is a surface-mount part. No socket option exists for this footprint, so swapping it on site means hot air or a fine-tipped iron — not a field-kit job unless you carry a hot-air station. MSL is not listed, but a 24-hour bake at 125°C before reflow is cheap insurance if the seal is broken. ## Lifecycle and sourcing The 74LV series is a mature logic family, but TI continues to support it.","metaTitle":"SN74LV157APW Multiplexer, 4 x 2:1, 2V-5.5V, 16-TSSOP","metaDescription":"Texas Instruments SN74LV157APW 4 x 2:1 multiplexer in 16-TSSOP. 2V to 5.5V supply, -40°C to 85°C.
