8BIT SERIAL−IN PARALLEL−OUT SHIFT REGISTER / LATCH DRIVERS
The TD62C853F and TD62C854F are monolithic circuits designed to be used together with Bi−
CMOS integrated circuits. The devices consist of a 8 bit shift register, 8 bit latches, and 8 output circuits.
FEATURES
l 8 bit serial−in parallel−out shift register / latch driver (Bi−
CMOS process)
l Maximum output sustaining
voltage ; 50 V
l Maximum output current ; TD62C853F 200 mA / ch (Low saturation type) TD62C854F 500 mA / ch (darlington type)
l
CMOS compatible inputs
l Package ; SSOP24−P−300−1.00
Weight: 0.32 g (Typ.)
Note:
S−OUT pin is sensitive against Latch−up. (Latch−up performance is under 30 mA) Please connect an external resistor to S−OUT pin in series due to protect this device from Latch−up. (Recommended resistance: R = 100 [Ω])
