HD14530BP CMOS Integrated Circuit IC DIP-16

Description

HD14530BP CMOS Integrated Circuit IC DIP-16 The HD14530BP is a dual five-input majority logic gate implemented in CMOS. Each gate evaluates five logic inputs (A–E) plus a control/test input W; the output Z is driven high when three or more inputs are logical “1.” The device’s monolithic CMOS structure uses P- and N-channel enhancement transistors and includes diode protection on every input. It accepts a wide supply range and can directly drive standard TTL loads. Functionally the HD14530BP simplifies many combinational and sequential circuits by providing majority-logic primitives (5-input and 3-input majority behavior) that can be reconfigured by tying inputs or using W as a control to realize OR, AND, NAND, NOR, XNOR and related functions with fewer external parts. The device incorporates static-protection circuitry to reduce ESD risk; the datasheet notes unused inputs must be tied to VSS or VDD. The datasheet covers plastic DIP-16, ceramic DIP and SOIC packages with full pin assignments (VDD = pin 16, VSS = pin 8) and outline drawings. Electrical data include input thresholds, VOH/VOL, drive currents, quiescent and dynamic supply currents, input capacitance, and timing (propagation delays and rise/fall times) at VDD = 5, 10 and 15 V. Example circuits shown include flip-flops and astable multivibrators. Features: Diode protection on all inputs. Wide operating supply range: 3.0 V to 18 V. Dual five-input majority logic gates (A–E inputs plus W control). Capable of driving two low-power TTL loads or one low-power Schottky-TTL load. Built-in static-protection circuitry (ESD protection). Unused inputs must be tied to a defined logic level (VSS or VDD).
