Frequently Asked Questions
What supply voltage does MT88L70ANR1 require and how does this benefit modern telecom designs?
The MT88L70ANR1 operates at a 3 V supply, aligning with modern low-voltage telecom system rails and reducing power dissipation compared to older 5 V DTMF receivers. This voltage compatibility simplifies integration with contemporary line-interface circuits and caller-ID modules that run from 3.3 V regulated supplies.
How many pins does the MT88L70ANR1 package have and what footprint does it occupy on a PCB?
The MT88L70ANR1 uses an SSOP-20 package with 20 pins and a shrink 0.635 mm pitch, resulting in a compact rectangular footprint suitable for space-constrained telephony PCBs. The small outline shrink style reduces board area versus standard DIP packages while maintaining compatibility with automated surface-mount assembly processes.
Which telephony and automation applications are best served by the MT88L70ANR1 DTMF receiver?
The MT88L70ANR1 suits applications including automated telephone answering systems, PBX line cards, POTS modems, and remote-monitoring units where DTMF tone decoding from 2-wire telephone lines is required. Its single-function design with 3 V operation and Pb-free compliance makes it a reliable choice for embedded telecom hardware.
What is the factory lead time for MT88L70ANR1 and how should procurement teams plan for it?
The MT88L70ANR1 carries an 11-week factory lead time, which is longer than many standard logic ICs. Procurement teams designing telecom equipment should place orders 12 to 14 weeks ahead of production start dates to account for shipping and incoming inspection, or qualify buffer stock strategies for high-volume builds.
