High–Performance Silicon–Gate CMOS
The MC74HC4511 is identical in pinout t o the MC14511 metal–gate
CMOS d ecoder/driver. The device inputs are c ompatible with standard
CMOS outputs; with pullup resistors, they are compatible with LSTTL
outputs.
The HC4511 provides the functions of a 4–bit storage latch, a BCD–to–
seven–segment decoder, and a display driver. It can be used either directly
or indirectly with seven–segment light–emitting diode (LED), incandescent,
fluorescent, g as discharge, or liquid–crystal readouts. Lamp test (LT),
blanking (BI), and latch enable (LE) inputs are used to test the display , to turn
off or pulse modulate the brightness of the display , and to store a BCD code,
respectively.
• Latch Storage of BCD Inputs
• Blanking Input
• Lamp Test Input
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 264 FETs or 66 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
