From the shop's description

SIEMENS SAB8284B-P Clock Generator and Driver for SAB 8086/8088 Processors +5V 110mA DIP-18 The SAB 8284B-P is a single-chip bipolar clock generator and driver designed for Siemens SAB 8086 and SAB 8088 processors and peripherals . Fabricated using Siemens’ fast bipolar ASBC (Advanced Standard Buried Collector) process, it integrates a crystal-controlled oscillator, divide-by-three counter, system reset logic with hysteresis, and bus READY synchronization logic . It uses 30% less power supply current than standard SAB 8284A devices . Features Full Compatibility Low Power Consumption High Clock Speed Support Flexible Clock Sources Multiple Clock Outputs Integrated Reset Logic Advanced READY Logic Multi-Chip Clock Synchronization Specifications Parameter Specification / Value Conditions / Details Power Supply Voltage (V CC ) +5V (±10%) Single +5V power supply Power Supply Current (I CC ) 110 mA (Max) All outputs open Power Dissipation 1.0 W (Max) Absolute maximum rating Clock Frequency Range Up to 8 MHz SAB 8284B-P model Input LOW Voltage (V IL ) 0.8 V (Max) Standard logic input Input HIGH Voltage (V IH ) 2.0 V (Min) Standard logic input Reset Input HIGH Voltage (V IHR ) 2.6 V (Min) Schmitt trigger input RES Input Hysteresis 0.25 V (Min) V IHR – V ILR Output LOW Voltage (V OL ) 0.45 V (Max) I = 5 mA Output HIGH Voltage (V OH ) 4.0 V (CLK) / 2.4 V (Other) I = -1 mA Operating Temperature (T A ) 0°C to +70°C Temperature under bias Storage Temperature -65°C to +150°C Storage conditions Applications System Clock Generation Bus & READY Synchronization Peripheral Synchronization Package Content 1 x SIEMENS SAB8284B-P Clock Generator and Driver for SAB 8086/8088 Processors +5V 110mA DIP-18 DataSheet SAB8284B
