In-Depth Product Analysis

Manufacturer Excellence

Nexperia, a global semiconductor leader, engineered the HEF4093BT,653 to meet stringent automotive-grade reliability standards (AEC-Q100 qualified). The IC's 14-SOIC package (3.90mm width) features lead-free plating and MSL 1 moisture sensitivity, ensuring manufacturing compatibility.

Technical Specifications Breakdown

Core Logic Architecture

• Quad 2-input NAND configuration with independent Schmitt Trigger inputs
• Hysteresis voltage: 0.9V (typ) at 5V supply for superior noise rejection
• Symmetrical trigger thresholds (VT+/VT- ratio: 1.78 typ at 5V)

Power Management

• Wide voltage range: 3V to 15V operation ( 0.5V tolerance)
• Ultra-low 1 A quiescent current (max at 5V)
• 3.4mA output drive (sinks/sources) at 5V for fan-out capability

Performance Metrics

• Propagation delay: 30ns typical (60ns max) at 15V/50pF
• Transition time: 20ns (rise/fall) at 15V
• Operating frequency: 25MHz typical at 10V

Comparative Advantages

Unlike standard NAND gates, the HEF4093BT,653's Schmitt Trigger inputs provide:

• 30% better noise margin than conventional CMOS
• Input hysteresis eliminates signal bounce in noisy environments
• Waveform squaring for degraded input signals
