Product details
Overview
EL7182CSZ 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 ≤25ns turn-on/turn-off delay, and supports TTL- and 3V-compatible inputs - enabling direct interface with microcontrollers and FPGA I/O in fax machines and industrial scanners.
For engineers reviewing the EL7182CSZ datasheet, EL7182CSZ pinout, EL7182CSZ application, or EL7182CSZ equivalent, key selection criteria include its 20ns switching time, dual-output push-pull architecture, SOIC-8 Pb-free package, low quiescent current (≤5mA), and compatibility with CCD clocking up to 10MHz under 15V supply.
Technical Context
The EL7182CSZ integrates two matched, high-current, complementary-output drivers in a single SOIC-8 package, each capable of sourcing and sinking 2A peak current. Its internal logic accepts asynchronous TTL/3V-compatible inputs and generates precisely timed, low-skew complementary outputs for CCD vertical/horizontal transfer clocks.
It features built-in hysteresis (0.3V) on input pins, rail-to-rail output swing (within 1.5V of rails), and thermal shutdown protection. The device is optimized for operation across -40°C to +85°C ambient, with junction temperature limited to 125°C and SOIC power dissipation rated at 570mW.
Key Specifications

IC Role / Device Role / Timing Role: Synchronized dual-output driver generating non-overlapping gate clocks for pixel charge transfer and readout. Use Value: 10MHz capability and 20ns switching enable sub-micron spatial resolution; wide supply range accommodates 12V system rails. |
| Differential Line Driver | Push-Pull Circuit for Analog Switch Control |
|
Use Scenario: Generating complementary high-speed differential signals for noise-immune transmission over 50Ω PCB traces or cables. IC Role / Device Role / Timing Role: Dual-channel complementary driver delivering matched rise/fall characteristics and amplitude symmetry. Use Value: Matched tR/tF (±1ns) and low skew ensure <50ps jitter in differential edge timing - critical for high-fidelity signal recovery. |
Use Scenario: Driving high-capacitance analog switches (e.g., multiplexers, sample-hold circuits) requiring fast, rail-swing control signals. IC Role / Device Role / Timing Role: High-current buffer converting logic-level enable/control signals into full-rail, low-impedance switch gate drives. Use Value: 2A peak current reduces switch turn-on time to <10ns, minimizing charge injection error in precision data acquisition paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EL7181CSZ | Single-phase version; identical SOIC-8 package, same 2A peak, 4.5–16V supply, but only one output pair | Suitable only for single-clock CCDs or where second phase is generated externally | Select when system requires only one high-current clock channel and board space is constrained |
| MAX4426ESA+ | Single 2A driver in SOIC-8; 3.3V–12V supply; no hysteresis; higher quiescent current (8mA) | Limited to lower-voltage CCDs; lacks dual-phase integration; requires external logic for phase generation | Choose for cost-sensitive, single-phase designs where 12V max supply suffices and timing skew is less critical |
Compared with EL7182CSZ, EL7181CSZ reduces channel count but retains identical drive strength and package, while MAX4426ESA+ trades voltage range and integrated dual-phase control for simpler single-channel use - making EL7182CSZ uniquely suited for compact, high-fidelity dual-clock CCD systems.

FAQ
What is the maximum clock frequency supported by the EL7182CSZ?
The EL7182CSZ supports clocking speeds up to 10MHz, as confirmed in the datasheet's Features section and validated by AC Electrical Specifications including tD-ON/tD-OFF ≤25ns and tR/tF ≤20ns under 1000pF load. This performance holds across the full 4.5V–16V supply range and -40°C to +85°C operating temperature.
Does the EL7182CSZ require external pull-up or pull-down resistors on its outputs?
No, the EL7182CSZ does not require external pull-up or pull-down resistors. Its outputs are true push-pull drivers with 3–6Ω pull-up (ROH) and 4–6Ω pull-down (ROL) on-resistance, enabling direct connection to CCD clock inputs without passive termination - verified by Electrical Specifications tables and Simplified Schematic in FN7281.
Is the EL7182CSZ pin-compatible with the EL7182CN or EL7182CS variants?
Yes, the EL7182CSZ shares identical pinout and electrical specifications with EL7182CN (PDIP-8) and EL7182CS (SOIC-8), differing only in Pb-free packaging and anneal process. All three use MDP0027 (SOIC) or MDP0031 (PDIP) package drawings and match on Pin 1–8 function mapping per the Top View diagram in FN7281 Rev 1.00.
What is the thermal derating behavior of the EL7182CSZ in SOIC-8 package?
The EL7182CSZ SOIC-8 package has a specified power dissipation limit of 570mW at TA = 25°C, with linear derating above 25°C at 5.7mW/°C (per Figure "Max Power/Derating Curves" on Page 4 of FN7281). Junction temperature must remain ≤125°C, requiring appropriate copper area and airflow in high-duty-cycle CCD applications.
Can the EL7182CSZ drive CCDs requiring >16V clock swing?
No, the EL7182CSZ has an absolute maximum supply rating of 16.5V and guaranteed operation up to 16V, as stated in Absolute Maximum Ratings and Electrical Specifications. It cannot safely drive CCDs requiring >16V clock swing; such applications require external level-shifting or higher-voltage driver ICs like the EL7155 or discrete MOSFET-based solutions.
