GENERAL DESCRIPTION

TheMSA4709AisdesignedtoprovideBSHfunctionsandtomeetPABXtransmissionperformance

requirements.

This device provides two-wire to four-wire conversion function (Hybrid).

FEATURES

• B (Battery feed), S (Supervision), and H (Hybrid) functions integrated on chip.

• Design to meet Central Office and PABX quality transmission requirements.

• All transmission performance parameters can be externally programmable.

• Free from parasitic SCR's using dielectric isolation technology.

• Size and weight reduction over conventional approaches.

• Supply voltage selectable (V = –24 V/–48 V).

• 1 channel built-in relay driver.

• Package:

30-pin plastic Shrink DIP (SDIP30-P-400-1.78) (Product name: MSA4709ASS)
