Dual independent N-channel gate driver in a through-hole DIP
The Renesas ICL7667CPAZ is a dual-channel gate driver designed to drive N-channel MOSFETs with inverting inputs and independent channel control. It comes in an 8-DIP (0.300", 7.62mm) through-hole package, making it suited for breadboard prototyping, legacy PCB retrofits, or designs where through-hole reliability is preferred over surface-mount. The two drivers operate independently, each with its own input, so you can drive separate MOSFETs in half-bridge or dual-switch configurations without cross-coupling concerns.
20 ns switching speed — what it buys you on the board
Typical rise and fall times of 20 ns each place this driver in the moderate-speed category. For a 12V rail switching a few amps into a motor or a buck converter running at 100 kHz to 300 kHz, 20 ns edges keep switching losses reasonable without creating the EMI headache of sub-5 ns drivers. The 4.5V to 15V supply range covers common logic and power rails, and the logic thresholds of 0.8V (VIL) and 2V (VIH) are TTL/CMOS-compatible, so a 3.3V or 5V microcontroller can drive the inputs directly.
Temperature grade — commercial only, no cold soak
Rated for 0°C to 70°C ambient, this is a commercial-temperature part. It belongs in office equipment, bench-top instruments, and indoor power supplies where the ambient never dips below freezing. If your design sees -20°C or +85°C, this driver is not the fit without additional thermal analysis or a switch to an extended-temperature variant.
Active lifecycle — no LTB clock ticking
The ICL7667CPAZ carries an Active product status and is ROHS3 compliant. There is no end-of-life notice, no last-time-buy deadline, and no successor part to chase. For a BOM line that needs a through-hole dual MOSFET driver, this part is a stable, in-production choice that can be specified into new designs without supply-chain anxiety.
