The game would continue to be closely contested until Cheng Bin and Chen Wan won four straight points to give themselves a 20-16 lead and with this, four match points. The second game began in a similar fashion to the first, with both sides exchanging blows in the early stages, with Cardiff Met taking a narrow 11-10 lead at the halfway stage. However, this was too little too late as the Sunderland duo completed a 21-17 victory to give themselves a one nil lead. At the halfway stage in the first game, Sunderland led 11-9 but this lead was quickly extended to 17-11 after a blistering spell for Cheng Bin and Chen Wan.Ī late rally from Lau and Wooding would reduce the deficit to just three points. The University of Sunderland pair came through a closely fought encounter, winning the first game 21-17 before edging out a nail biting second game 23-17 to beat Gareth Lau and Ben Wooding.Ĭheng Bin and Chen Wan came into the game knowing only a victory would secure their passage into the next round of the competition.ĭespite this pressure, both sides began the match in good form, going toe to toe in the early stages. The required input current is below that of the SN75468.Tee Cheng Bin and Lee Randy Chen Wan started their journey to the Round of 32 of the BUCS Nationals after a straight set victory over Cardiff Metropolitan University.

#Darlington transistor ac series#

The SN75469 has a 10.5-kΩ series base resistor to allow its operation directly with CMOS or PMOS that use supply voltages of 6 to 15 V. The SN75468 has a 2700-Ω series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS.

#Darlington transistor ac drivers#

Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. The Darlington pairs may be paralleled for higher current capability. The collector-current rating of each Darlington pair is 500 mA. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The SN75468 and SN75469 are high-voltage, high-current Darlington transistor arrays.
