Hello Vidhya,

SN74CBTLV3253RGYR is the 2-bit version of SN74CBTLV3257RGYR. 

Here is the datasheet: https://www.ti.com/lit/ds/symlink/sn74cbtlv3253.pdf?ts=1693499369749&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FSN74CBTLV3253 

Thanks,

Here is a search for two-channel, 2:1, 3.3 V switches: ti.com/switches-multiplexers/analog/products.html#480=2&1143=2:1 SPDT&3306=3.3 Use the TS3A5223 or TS5A23157, depending on how much bandwidth you need.

Yes, here are some suggestions:

TS3A24159 - https://www.ti.com/lit/ds/symlink/ts3a24159.pdf?ts=1693926639393&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTS3A24159 

TS3A24157 - https://www.ti.com/lit/ds/symlink/ts3a24157.pdf?ts=1693926641524&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTS3A24157 

TS3A5223 - https://www.ti.com/lit/ds/symlink/ts3a5223.pdf?ts=1693926644517&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTS3A5223 

Please note, these devices work at a lower voltage supply than the SN74CBTLV3257RGYR (3.3V vs 3.6V), but they have lower Ron.

Also they are in different packages than SN74CBTLV3257RGYR and not p2p replacements. 

Best,

Nir
