PRODUCT OVERVIEW
The NMTTLD6S5MC is a low power electrically
isolated TTL data transmission device. No external
components are needed as a single 5V supply
powers all functions either side of the isolation
boundary. NMTTLD655MC also provides a
regulated 5V, unregulated 6V and -6V isolated
supply’s for system use.

TECHNICAL NOTES
ISOLATION VOLTAGE
‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test
voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Murata Power Solutions NMTTLD6S5MC data isolator is 100% production tested at 1.5kVAC rms for 1 second and have been qualification tested at 1.5kVAC rms for 1
minute.
The NMTTLD6S5MC
is pending recognition by Underwiters Laboratory to 250 Vrms basic Insulation.
REPEATED HIGH-VOLTAGE ISOLATION TESTING
It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on
materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be
reduced by 20% from specified test voltage.
SAFETY APPROVAL
ANSI/AAMI ES60601-1
The NMTTLD6S5MC is pending recognition ANSI/AAMI ES60601-1 and provides 1 MOPP (Means Of Patient Protection) and 1 MOOP (Means Of Operator Protection) based upon a
working voltage of 250 Vrms max, between Primary and Secondary.
UL 60950
The NMTTLD6S5MC is pending recognition by Underwriters Laboratory (UL) to UL 60950 for basic insulation to a working voltage of 250Vrms.
FUSING
The NMTTLD6S5MC is not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below.
NMTTL - 1A
All fuses should be UL recognized and rated to at least the maximum allowable DC input voltage.
RoHS COMPLIANCE, MSL AND PSL INFORMATION
The NMTTLD6S5MC is compatible with Pb-Free soldering systems and is also backward compatible with Sn/Pb soldering
systems. The NMTTLD6S5MC has a process, moisture, and reflow sensitivity classification of MSL2 PSL R7F as defined in
J-STD-020 and J-STD-075. This translates to: MSL2 = 1 year floor life, PSL R7F = Peak reflow temperature 245°C with a
limitation on the time above liquidus (217°C) which for this series is 90sec max. The pin termination finish on this product
series is Gold with Nickel Pre-plate.
