the conventional linear process. This allows simultaneous
fabrication of high-speed TTL gates with a precision linear amplifier
on a single monolithic chip.

FEATURES

•10ns propagation delay

•Complementary output gates

•TTL or ECL compatible outputs

•Wide common-mode and differential voltage range

•Typical gain 5000

APPLICATIONS

•A/D conversion

•ECL-to-TTL interface

•TTL-to-ECL interface

•Memory sensing

•Optical data coupling

APPLICATIONS

One of the main features of the device is that supply voltages (V+,
V-) need not be balanced, as in the following diagrams. For proper
operation, however, negative supply (V-) should always be at least
6V more than the ground terminal (pin 6). Input Common-Mode

range should be limited to values of 2V less than the supply voltages
(V+ and V-) up to a maximum of ±5V as supply voltages are
increased.

It is also important to note that Output A is in phase with Input A and
Output B is in phase with Input B.
