Part identity and what it does
The TP3465V is a microprocessor circuit in a 28-lead PLCC package (J-lead, 11.51 x 11.51 mm body) for ISDN applications.
Lifecycle status — still active, but niche
For ISDN infrastructure still in the field — remote telemetry, industrial PBX, legacy telecom — this part remains a valid BOM line.
The 28-PLCC with J-leads is a surface-mount package. The 11.51 x 11.51 mm footprint is standard for 28-PLCC. Bulk shipment means the parts arrive loose.
