Product details
Overview
HA4600CBZ from Intersil is a unity-gain video buffer IC with TTL-compatible enable input, 480MHz -3dB bandwidth, 0.01%/0.01° differential gain/phase, and high-impedance output disable mode. It operates at ±5V supply, delivers 1750/1770 V/µs symmetric slew rate, and is optimized for professional video routing in SOIC-8 packaging.
For engineers reviewing the HA4600CBZ datasheet, HA4600CBZ pinout, HA4600CBZ application, or HA4600CBZ equivalent, key selection criteria include off-isolation (85dB @ 100MHz), low power dissipation (105mW enabled / 100µA disabled), ±2.8V output swing, and compatibility with 75Ω video termination networks in matrix switcher designs.
Technical Context
The HA4600CBZ implements a fully differential, current-feedback architecture enabling wideband operation up to 480MHz while maintaining 0.1dB gain flatness to 250MHz. Its enable-controlled output stage disconnects the internal amplifier core from the output node, achieving >12MΩ disabled output resistance and 2.0pF disabled capacitance for minimal crosstalk in multiplexed video paths.
Designed for use with external 75Ω source/load terminations, the HA4600CBZ requires no internal feedback resistors and exhibits 400kΩ input resistance and 1.0pF input capacitance-critical for preserving signal integrity across long PCB traces in HDTV and computer graphics routing applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HA4600CHZ96 | SOT-23-6 package; higher θJA (210°C/W); same electrical specs; marking "46Z" | Space-constrained PCBs where SOIC-8 footprint is prohibitive; lower thermal mass limits continuous drive capability | Select HA4600CHZ96 only when board area is critical and average power dissipation remains <50mW |
| HA4201CPZ | Includes tally output (TALLY pin); PDIP-8 package; identical AC/DC specs except tally logic overhead | Systems requiring visual enable-status indication (e.g., front-panel LEDs synchronized to video path activation) | Choose HA4201CPZ when status feedback is required; HA4600CBZ preferred for pure buffering without extra pins |
Compared with HA4600CHZ96 and HA4201CPZ, the HA4600CBZ provides optimal thermal performance in SOIC-8 for sustained video routing, avoids tally-related complexity, and maintains full pin compatibility with legacy HA4600CPZ layouts-enabling drop-in replacement without redesign.

FAQ
What is the maximum operating temperature range for the HA4600CBZ?
The HA4600CBZ is rated for operation from 0°C to +70°C ambient temperature. Its maximum junction temperature is 150°C in the plastic SOIC package, and thermal resistance θJA is 170°C/W. For reliable long-term performance in video routing equipment, ensure board-level airflow or copper pour meets this thermal limit when dissipating 105mW in enabled mode. The HA4600CBZ must not be operated outside its specified temperature range.
Does the HA4600CBZ require external feedback resistors to operate as a unity-gain buffer?
No, the HA4600CBZ is internally configured as a unity-gain buffer and contains no internal feedback or gain-setting resistors. It is designed to operate directly with 75Ω source and load terminations-no external resistors are needed for basic functionality. The HA4600CBZ achieves its specified 480MHz bandwidth and 0.01% differential gain error only when used in this configuration, as validated in the FN3990 datasheet test circuits.
How does the enable function affect power consumption in the HA4600CBZ?
When enabled (EN = 2.0V), the HA4600CBZ draws 10.5mA typical supply current (105mW at ±5V). When disabled (EN = 0.8V), supply current drops to 100µA typical (1mW), reducing power by two orders of magnitude. This low-disabled-state current allows the HA4600CBZ to remain powered while inactive in large video matrices without thermal or efficiency penalties. The HA4600CBZ datasheet confirms this behavior across 0°C to +70°C.
Can the HA4600CBZ drive 75Ω coaxial cables directly?
Yes-the HA4600CBZ is explicitly characterized for 75Ω video termination. Its 15Ω enabled output resistance, ±2.8V output swing, and 1750 V/µs slew rate allow direct driving of 75Ω coaxial lines up to 10 meters with minimal distortion. The FN3990 datasheet specifies performance using 75Ω source/load resistors and recommends short trace lengths to preserve 480MHz bandwidth. The HA4600CBZ achieves 0.01% differential gain error under these conditions.
Is the HA4600CBZ pin-compatible with the obsolete HA4600CPZ?
Yes-the HA4600CBZ uses the same SOIC-8 package (M8.15) and identical pinout as the discontinued HA4600CPZ (PDIP-8), making it a direct drop-in replacement for legacy designs. Both share identical pin assignments: EN (1), V− (2), V+ (3), OUT (4), NC (5), IN (6), GND (7), NC (8). The HA4600CBZ retains all electrical specifications while upgrading to Pb-free RoHS compliance and improved thermal performance over the through-hole HA4600CPZ.
