Description
OPTOLOGIC™ is the first family of truly logic compatible
optically coupled logic interface gates.
74OL6000
74OL6001
74OL6010
74OL6011
The family consists of four device types offering LSTTL
to TTL and LSTTL to CMOS interfacing. Each of these
interfacing functions is available as a buffer (A = B), or
as an inverter (A = B).
Features
The LSTTL input compatibility is provided by an input
integrated circuit, with industry standard logic levels.
This input amplifier IC switches a temperature compen-
sated current source driving a high speed 850nm
AlGaAs LED emitter. This novel integration scheme
eliminates CTR degradation over time and temperature.
■ Industry first LSTTL to TTL and LSTTL to CMOS
complete logic-to-logic optocoupler
■ Incorporates LED drive circuitry — use as a logic gate
■ Very high speed
■ Choice of buffer or inverter
■ Choice of TTL or CMOS compatible output up to 15
The emitter is optically coupled to an integrated photode-
tectorꢁhigh-gain, high-speed output amplifier IC. The
superior 15ꢀVꢁ/S common-mode noise rejection is
ensured through the use of an optically transparent
noise shield.
volts
■ Fan-out of 10 TTL loads, fan-in 1 LSTTL load
■ Internal noise shield — very high CMR of 15ꢀVꢁ/S
■ UL recognized (File #E90700)
■ Same noise immunity as LSTTLꢁTTL.
The TTL compatible output has a totem-pole with a
fan-out of 10. The CMOS compatible output has an open
collector Schottꢀy-clamped transistor that interfaces to
any CMOS logic between 4.5 and 15 volts. The
74OL6010ꢁ11 may also by used to drive power MOSFETs
or transistors up to 15 volts.
Applications
■ Transmission line interface — receiver and driver
■ Excellent as bridged receiver in fast LAN highways
■ Bus interface
The Optologic coupler family typically offers propagation
of delays of 60 ns and can support 15 MBaud data
communication.
■ Logic family interface with ground loop noise
elimination
■ High speed ACꢁDC voltage sensing
■ Driver for power semiconductor devices
■ Level shifting
The two input chips and the output chip are assembled
in a 6-pin DIP high insulation voltage plastic pacꢀage.
