Renesas EL7182CSZ-T7

Overview

EL7182CSZ-T7 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 supports TTL/3V-compatible inputs - enabling direct interface with FPGA or microcontroller clock generators in fax machines and industrial scanners.

For engineers reviewing the EL7182CSZ-T7 datasheet, EL7182CSZ-T7 pinout, EL7182CSZ-T7 application, or EL7182CSZ-T7 equivalent, key selection criteria include its 10MHz maximum clocking speed, dual-output push-pull architecture with matched rise/fall times (7.5–20ns), low quiescent supply current (2.5–5mA), and Pb-free SOIC-8 packaging qualified for reflow at Pb-free peak temperatures.

Technical Context

The EL7182CSZ-T7 implements two independent, complementary-output drivers with matched propagation delays (tD-ON/tD-OFF ≤25ns) and reduced clock skew - critical for maintaining phase alignment in 2-phase CCD pixel transfer clocks. Its pull-up (ROH: 3–6Ω) and pull-down (ROL: 4–6Ω) resistances are optimized for fast edge rates into capacitive loads up to 1000pF.

It functions as a high-voltage, high-slew-rate line driver with rail-to-rail output swing capability across its 4.5V–16V supply range, supporting both source and sink operation up to 2A peak per channel while maintaining stable DC output current (100mA continuous) and low input hysteresis (0.3V).

Key Specifications

Pinout & Package

EL7182CSZ-T7 is housed in an 8-lead SOIC package (MDP0027), RoHS-compliant with 100% matte tin termination, rated MSL-3 for Pb-free reflow.

Equivalent & Alternatives

The following parts are listed as comparable options for similar CCD driver applications.

Compared with EL7182CSZ-T7, EL7181CSZ-T7 provides half the functionality in identical packaging but avoids redesign if only one phase is needed, while MAX4392EUD+ demands significant external circuitry and offers no native 2-phase synchronization - making EL7182CSZ-T7 the only production-ready, drop-in solution for dual-phase CCD timing.

FAQ

What is the maximum clock frequency supported by the EL7182CSZ-T7?

The EL7182CSZ-T7 supports clocking speeds up to 10MHz, as confirmed in the datasheet's Features section and validated by AC electrical specifications including rise/fall time and delay measurements at that frequency. This makes EL7182CSZ-T7 suitable for high-speed CCD line readout in modern imaging systems where timing precision and edge rate are critical.

Is the EL7182CSZ-T7 pin-compatible with the EL7182CSZ or EL7182CS variants?

Yes - EL7182CSZ-T7 shares identical pinout, electrical characteristics, and SOIC-8 package (MDP0027) with EL7182CSZ and EL7182CS. The "-T7" suffix denotes 7-inch tape-and-reel packaging; all three variants are functionally and mechanically interchangeable on PCBs designed for the SOIC-8 footprint.

Does the EL7182CSZ-T7 require external pull-up or pull-down resistors on its inputs?

No - the EL7182CSZ-T7 features TTL- and 3V-compatible inputs with defined VIH (≥2.4V) and VIL (≤0.8V) thresholds and low input leakage (0.1–10µA), eliminating the need for external biasing. Its 0.3V input hysteresis further enhances noise immunity without external components, simplifying integration with EL7182CSZ-T7 in FPGA- or MCU-driven timing systems.

What thermal derating applies to the EL7182CSZ-T7 in SOIC-8 package?

The EL7182CSZ-T7 in SOIC-8 has a maximum power dissipation of 570mW at TA = 25°C, with linear derating above 25°C at 4.56mW/°C (per the datasheet's Power Dissipation table). Designers must ensure board layout provides adequate copper area and airflow to maintain junction temperature ≤125°C, especially under sustained 2A peak output conditions.

Can the EL7182CSZ-T7 drive CCDs requiring >16V supply rails?

No - the absolute maximum supply rating for EL7182CSZ-T7 is 16.5V, and recommended operating voltage is limited to 4.5V–16V. Driving CCDs requiring >16V rails would exceed absolute maximum ratings and risk permanent damage. For higher-voltage CCDs, alternative drivers such as the EL7183 (20V-rated) or discrete MOSFET-based solutions must be used instead of EL7182CSZ-T7.
