♦Inputs Fully Compatible With Most TTL Circuits
Description
These hex inverter buffers/drivers feature high-voltage open-
collector outputs to interface with high-level circuits (such as
MOS), or for driving high-current loads, and also are
characterized for use as inverter buffers for driving TTL inputs.
The ’LS06 devices have a rated output voltage of 30 V, and
the SN74LS16 has a rated output voltage of 15 V. The
maximum sink current for the SN54LS06 is 30 mA, and for the
SN74LS06 and SN74LS16 is 40 mA. These devices are
compatible with most TTL families. Inputs are diode-clamped to
minimize transmission effects, which simplifies design. Typical
power dissipation is 175 mW and average propagation delay time is 8
ns.
