HEX BUFFERS/DRIVERS
WITH OPEN-COLLECTOR HIGH-VOLTAGE OUTPUTS
description
These monolithic TTL hex buffers/drivers feature
high-voltage open-collector outputs for interf acing
with high-level circuits (such as MOS or Hi NIL).
or for driving high-current loads (such as lamps or
relays). and are also characterized for use as buffers
for driving TTL inputs. For increased fan-out.
several buffers in a single package may be paralleled.
The ITT5407 and ITT7407 have minimum
breakdown voltages of 30 volts and the ITT5417
and ITT7417 have minimum breakdown· voltages
of 15 volts. The maximum sink current is 30
recommended operating conditions
Supply voltage Vee
milliamperes for the ITT5407 and ITT5417. and 40
milliamperes for the ITT7407 and ITT7 417.
These circuits are completely compatible with most
TTL or DTL families. Inputs are diode-clamped to
minimize transmission-line effects which simplifies
design. Typical power dissipation is 145 milliwatts
and average propagation delay time is 14 nanoseconds.
The ITT5407 and ITT541.7 are characte rized
for operation over the full military temperature
range of -55°C to 125°C; the ITT7407 and ITT-
7417 are characterized for operation from O°C to
70°C.
