Product details
Overview
EL7156CS-T7 from Intersil is a high-performance 40MHz analog pin driver with three-state control, designed for ATE/burn-in testers and level-shifting applications. It delivers 3.5A peak drive current, features 3.5Ω typical ON-resistance (VH→OUT), and operates across -40°C to +85°C with independent VH/VL voltage rails up to 16.5V differential.
For engineers reviewing the EL7156CS-T7 datasheet, EL7156CS-T7 pinout, EL7156CS-T7 application, or EL7156CS-T7 equivalent, key selection criteria include its 15ns rise/fall time at 2000pF load, 0.5ns tR/tF mismatch, three-state enable timing (10ns), and SOIC-8 package compatibility with Pb-free reflow processing.
Technical Context
The EL7156CS-T7 implements dual N-channel MOSFET switches controlled by IN and OE logic inputs, enabling VH or VL to be routed to OUT based on IN state while OE disables both paths simultaneously. Its isolated VS− pin allows VL to operate down to −5V relative to GND, decoupling level-shift boundaries from ground reference.
Switching performance is optimized via low input capacitance (3.5pF) and matched propagation delays (td−1/td−2 mismatch ≤0.5ns), supporting precise timing in high-speed digital test systems. The device maintains sub-5Ω ON-resistance across 4.5V–16.5V supply range while sustaining 200mA continuous output current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Clock Frequency | 40MHz - supports high-speed ATE pattern rates without timing violation |
| Rise/Fall Time (2000pF) | 14.5/15ns - enables fast edge transitions into heavy capacitive loads |
| tR/tF Mismatch | 0.5ns - ensures minimal skew between rising and falling edges for balanced signal integrity |
| ON-Resistance (VH→OUT) | 2.7Ω (min), 4.5Ω (max) - reduces conduction loss and voltage drop during active drive |
| Peak Output Current | 3.5A - sustains transient current surges when charging large load capacitances |
| Supply Voltage Range | VS+ to VS−: 4.5V–16.5V - accommodates wide-level shift ranges including ±5V configurations |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automated test equipment environments |
Pinout & Package
EL7156CS-T7 is housed in an 8-lead Pb-free SOIC package (MDP0027), measuring 0.193" × 0.236" with 0.050" lead pitch. Thermal resistance θJA is 160°C/W on JEDEC JESD51-3 board, requiring careful power dissipation management above 1MHz switching or >1nF loads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VS+) | Positive supply rail | Primary power input; must be bypassed with 0.1µF ceramic + 2.2µF tantalum near pin |
| 2 (OE) | Output enable control | Active-low signal placing OUT in high-impedance state; 10ns enable/disable delay |
| 3 (IN) | Logic select input | Determines connection: IN=1 routes VL→OUT; IN=0 routes VH→OUT (per truth table) |
| 4 (GND) | Reference ground | Signal return path; separate from VS− but referenced in input threshold specs |
| 5 (VS−) | Negative supply rail | Enables VL to operate as low as −5V; isolates level-shift domain from GND |
| 6 (VL) | Lower output voltage rail | Independent voltage source connected to OUT when IN=1; must be < VH to avoid body diode conduction |
| 7 (OUT) | Switched output terminal | Drives external load; capable of sourcing/sinking 3.5A peak with 3.5Ω typical RON |
| 8 (VH) | Higher output voltage rail | Independent voltage source connected to OUT when IN=0; sets upper logic level for level shifting |
Key Features
| Feature | Design Value |
|---|---|
| Three-state output control | OE pin provides 10ns enable/disable timing for synchronized bus isolation in multi-driver systems |
| Independent VH/VL rails | VH and VL can be set independently between VS− and VS+, enabling asymmetric level shifts (e.g., −5V to +15V) |
| Low ON-resistance matching | VH→OUT and VL→OUT RON differ by <1Ω typical, minimizing duty-cycle distortion in AC-coupled signals |
| High capacitive drive capability | Validated at 2000pF load with 15ns transitions - suitable for driving long PCB traces or IGBT gate networks |
| Pb-free RoHS compliance | Matte tin termination compatible with SnPb and Pb-free reflow profiles per J-STD-020 |
Applications
| ATE/Burn-in Testers | Level-Shifting Interfaces |
|---|---|
|
Use Scenario: Driving DUT pins during functional testing with programmable voltage levels and fast edge rates. IC Role / Device Role / Timing Role: Pin driver providing bidirectional level translation between tester logic and device-under-test I/O rails. Use Value: 40MHz clocking and 15ns transitions ensure accurate timing margin validation across voltage domains. |

IC Role / Device Role / Timing Role: Analog switch implementing VH/VL-selectable output routing with three-state isolation. Use Value: Independent VH/VL rails allow arbitrary level placement (e.g., VL = −2V, VH = +10V), eliminating external level-shift components. |

Use Value: 0.5ns tR/tF mismatch and 10ns three-state delay support pixel clock synchronization in high-resolution imaging systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EL7155CSZ | Lacks VS− pin and isolated VL rail; VL tied to GND or VS− internally | Cannot support negative VL or asymmetric level shifts; limited to single-supply operation | Select EL7155CSZ only if VL = GND or VS− is sufficient and cost sensitivity outweighs flexibility needs |
| MAX4893ESE+ | Lower peak current (2A), higher RON (8Ω), no VS− pin; TTL/CMOS compatible inputs | Better suited for low-power logic-level translation than high-current switching or wide-level shift | Choose MAX4893ESE+ for space-constrained 16-pin SOIC designs where 3.5A drive is unnecessary |
Compared with EL7156CS-T7, EL7155CSZ sacrifices level-shift flexibility and peak drive for lower cost and simpler biasing, while MAX4893ESE+ trades drive strength and rail independence for broader logic compatibility and smaller footprint - making EL7156CS-T7 optimal for demanding ATE and high-current level-shifting where precision timing and wide voltage range are critical.

FAQ
What is the maximum allowable voltage difference between VH and VL for EL7156CS-T7?
The EL7156CS-T7 specifies VH to VL operating range up to 16.5V per the "Operating Voltage Range" table on page 6 of FN7280 Rev 4.00. Exceeding this may cause breakdown or reliability degradation. VH must always be greater than VL to prevent body diode conduction at the output stage, and both must remain within VS− to VS+ limits.
Does EL7156CS-T7 support negative VL voltages, and how is that implemented?
Yes, EL7156CS-T7 supports VL as low as −5V relative to GND, enabled by its dedicated VS− pin. When VS− is biased below GND (e.g., −5V), VL may be set to that same potential, allowing true bipolar level shifting. This architecture isolates VL from GND and avoids the body diode turn-on that would occur in single-supply alternatives like EL7155CSZ.
What is the recommended power supply bypassing configuration for EL7156CS-T7?
Per page 8 of FN7280 Rev 4.00, EL7156CS-T7 requires a 0.1µF low-inductance ceramic capacitor in parallel with a 2.2µF tantalum capacitor between VS+ and VS−, placed as close as possible to pins 1 and 5. Additional local bypassing (e.g., 0.1µF) is advised at VH and VL pins when driving >500pF loads to suppress ringing and maintain switching fidelity.
How does the three-state behavior of EL7156CS-T7 affect output voltage during OE = low?
When OE = low, EL7156CS-T7 places OUT in high-impedance mode. The output voltage floats at whatever potential remains on its parasitic capacitance - typically the last driven level (between VH and VL). It cannot be forced beyond VH or below VL due to internal body diodes, and no active clamping is provided; external hold-down or pull-up networks may be required for defined idle states.
Is EL7156CS-T7 pin-compatible with EL7156CNZ or EL7156CSZ?
Yes, EL7156CS-T7 shares identical 8-lead SOIC pinout and electrical specifications with EL7156CSZ and the discontinued EL7156CNZ (PDIP-8). All variants use the same die and functional design; only package (SOIC vs PDIP) and packaging format (tape-and-reel vs tube) differ. No PCB layout changes are needed when migrating from EL7156CSZ to EL7156CS-T7.
