ON MC100ELT24 5v ttl to differential ecl translator Datasheet

MC10ELT24, MC100ELT24
5VTTL to Differential
ECL Translator
The MC10ELT/100ELT24 is a TTL to differential ECL translator.
Because ECL levels are used a +5 V, −5.2 V (or −4.5 V) and ground
are required. The small outline 8−lead package and the single gate of
the ELT24 makes it ideal for those applications where space,
performance and low power are at a premium.
The 100 Series contains temperature compensation.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
