BCD-to-7 Segment Latch/Decoder/Driver
The TC74HC4511A is a high speed CMOS BCD-TO-7
SEGMENT LATCH/DECODER/DRIVER fabricated with silicon
gate C2MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The segment output driver, which is of CMOS construction, has
a large IOH capability which permits the device to drive cathode
common LED directly.
When lamp test (LT) is held low, all segment outputs will go
high, and when the blanking input (BI) is held low and LT is held
high, all segment outputs will go low. These functions are
independent of other inputs and used to test the display.
BI is used to pulse - modulate the brightness of the display.
When error code (over 10) is applied to BCD inputs, all
segment outputs will go to low (turn off).
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: tpd = 28 ns (typ.) at VCC = 5 V

• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = 20 mA
• Wide operating voltage range: VCC (opr) = 2 to 6 V
• Pin and function compatible with TC4511B
