The GTL202x is intended to provide GTL bus termination in multi-processor environments. The enable pins allow the system control to disconnect the bus termination. When the bus switch is enabled, a 56, 75, 100 or 150 Ω series resistance is connected to the GTL Vbias. 42 VCC EN2 16 41 VBIAS2B A16 17 40 A20 A17 18 39 A21 A18 19 38 A22 A19 20 37 A23 GND 21 36 NC VBIAS3A 22 35 VCC EN3 23 34 VBIAS3B A24 24 33 A28 A25 25 32 A29 A26 26 31 A30 A27 27 GND 28 30 A31 29 NC SW00473 QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER TYPICAL UNIT Bus enable/disable CL = 20 pF, RL = 500 Ω 2.5 nS CON Input capacitance switch on VIN = 0 V 3 pF COFF Input capacitance switch off VIN = 0 V 6 pF tPE/PD ORDERING INFORMATION PACKAGES TEMPERATURE RANGE ORDER CODE DWG NUMBER 56-Pin Plastic TSSOP Type II –40°C to +85°C GTL2020 DGG SOT364-1 56-Pin Plastic TSSOP Type II –40°C to +85°C GTL2021 DGG SOT364-1 56-Pin Plastic TSSOP Type II –40°C to +85°C GTL2022 DGG SOT364-1 56-Pin Plastic TSSOP Type II –40°C to +85°C GTL2023 DGG SOT364-1 2000 Jan 14 2 Philips Semiconductors Product specification GTL2020/GTL2021/ GTL2022/GTL2023 32-bit GTL terminator with octal enables LOGIC DIAGRAM FUNCTION TABLE ENn R A0 VBIAS0A VBIAS0B EN0 R A8 L ON H OFF NOTES: When enabled: Ports Ax connect to VBIASnA Ports Ay connect to VBIASnB Where: X = 0–3, 8–11, 16–19, 24–27 Y = 4–7, 12–15, 20–23, 28–31 R A7 SWITCH VBIAS1A R A15 VBIAS1B EN1 R A16 VBIAS2A R A23 VBIAS2B EN2 R A24 VBIAS3A R A31 VBIAS3B EN3 SW00474 Figure 1.
