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

NOTE: Information on typical parametric values can be found in Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).

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.
