• Each Device Drives 12 Lines
• 60-V Output Voltage Swing Capability
• 25-mA Output Source Current Capability
• High-Speed Serially-Shifted Data Input
• TTL-Compatible Inputs
• Latches on All Driver Outputs
The SN65512C and SN75512C are monolithic
BIDFET† integrated circuits designed to drive a
dot matrix or segmented vacuum fluorescent
All device inputs are diode-clamped pnp inputs
and assume a high logic level when open
circuited. The nominal input threshold is 1.5 V.
Outputs are totem-pole structures formed by an
npn emitter follower and double-diffused MOS
The device consists of a 12-bit shift register,
12 latches, and 12 output AND gates. Serial data
is entered into the shift register on the low-to-high
transition of CLOCK. When high, LATCH ENABLE
transfers the shift register contents to the outputs
of the 12 latches. The active-low STROBE input
enables all Q outputs. Serial data output from the
shift register can be used to cascade shift
registers. This output is not affected by LATCH
ENABLE or STROBE.
The SN65512C is characterized for operation
from − 40°C to 85°C. The SN75512C is
characterized for operation from 0°C to 70°C.
