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

SN74LS90/SN74LS92/SN74LS93 pdf

The SN74LS90/SN74LS92/SN74LS93 are high-speed4-bit ripple type counters partitioned into two sections. Each counter has a divide-by-two section and either a divide-by-five (LS90),
