Renesas EL7182CN

Overview

EL7182CN from Intersil is a 2-phase, high-speed CCD driver IC designed for precision charge-coupled device timing control in high-contrast imaging systems. It operates from 4.5V to 16V, delivers 2A peak output current per phase, achieves ≤20ns switching/delay time, and accepts TTL/3V-compatible inputs - making it ideal for color fax machine CCD biasing and portable imaging front-ends.

For engineers reviewing the EL7182CN datasheet, EL7182CN pinout, EL7182CN application, or EL7182CN equivalent, key selection criteria include its 10MHz clocking capability, low quiescent current (≤5mA), dual-phase push-pull drive architecture, and PDIP-8 package compatibility with legacy CCD timing layouts.

Technical Context

The EL7182CN implements a dual-channel, complementary-output driver stage optimized for CCD vertical/horizontal transfer clock generation. Each channel provides independent source/sink capability with matched pull-up (3–6Ω) and pull-down (4–6Ω) resistances, enabling precise edge alignment and reduced clock skew between phases.

It features hysteresis (0.3V) on digital inputs for noise immunity, supports operation across –40°C to +85°C, and maintains stable drive performance under capacitive loads up to 1000pF with rise/fall times of 7.5–20ns depending on load and supply voltage.

Key Specifications

Pinout & Package

EL7182CN is housed in an 8-lead Plastic Dual-In-Line Package (PDIP) per package drawing MDP0031, with 0.300" body width, 0.100" lead pitch, and through-hole mounting compatibility.

FAQ

What is the maximum clock frequency supported by the EL7182CN?

The EL7182CN supports clocking speeds up to 10MHz, verified under typical conditions (V+ = 15V, TA = 25°C). Its 18–25ns propagation delay and 7.5–20ns rise/fall times enable reliable operation at this rate with appropriate load capacitance (≤1000pF). Performance remains stable across the full –40°C to +85°C temperature range, though timing margins should be validated in final system layout.

Does the EL7182CN require external pull-up or pull-down resistors on its inputs?

No, the EL7182CN does not require external pull-up or pull-down resistors on IN1 or IN2. Its inputs feature built-in hysteresis (0.3V) and specify VIH ≥ 2.4V and VIL ≤ 0.8V, ensuring robust TTL/3V logic compatibility. Input leakage is low (≤10µA), so direct connection to FPGA or microcontroller GPIOs is fully supported without additional biasing components.

Can the EL7182CN drive both N-channel and P-channel CCD clock lines simultaneously?

Yes - the EL7182CN provides true complementary push-pull outputs (OUT1 and OUT2), each capable of sourcing and sinking up to 2A peak current. This architecture directly supports driving both N- and P-channel CCD clock inputs without external transistors, provided the CCD's voltage swing requirements fall within the EL7182CN's 4.5V–16V supply range and load capacitance stays within spec.

Is the EL7182CN pin-compatible with other members of the EL718x family?

Yes, the EL7182CN shares identical pinout and functionality with EL7182CS and EL7182CSZ across all 8 pins, including the NC pin (Pin 8). Electrical specifications, timing behavior, and thermal limits are identical - only package type (PDIP vs SOIC) and termination finish (SnPb vs matte tin) differ. No PCB redesign is needed when migrating between these variants.

What thermal considerations apply to the EL7182CN in continuous operation?

In continuous operation, the EL7182CN's PDIP-8 package has a maximum power dissipation of 1050mW at TA = 25°C, derating linearly above that temperature. Junction temperature must stay ≤125°C. For sustained 2A peak loads at high duty cycles, board-level copper pour and airflow should be verified. Thermal resistance θJA is ~120°C/W (PDIP), so at 500mW dissipation, ΔT ≈ 60°C above ambient - requiring careful layout in enclosed or high-temperature environments.
