ZXFBF05 4 Channel Buffer Device with high capacitance load capability APPLICATIONS DEVICE DESCRIPTION The ZXFBF05 is a low cost, high slew rate, quad buffer amplifier. Built using the Zetex CA700 technology, this buffer has a small signal bandwidth of greater than 100MHz and a 1 volt pk-pk bandwidth of greater than 20 MHz. Each channel draws only 7.5mA. The device operates from a ±5 volt supply, which makes it ideal in a majority of applications. This space saving buffer may be used in a wide variety of applications such as, video switching matrix, multi-channel instrumentation equipment, and A/D input buffer, etc. FEATURES AND BENEFITS • Video Switching Matrix input buffer • Instrumentation • Multi-channel A/D input buffer • Multi-isolation buffer PART NUMBER PACKAGE PART MARK ZXFBF05N14 SOIC14N ZXFBF05 ORDERING INFORMATION • 4 Buffers per package • Low distortion Class A O/P • 100MHz bandwidth • Low cost • Designed for up to 300pF load • Low supply current (7.5mA per buffer) • No thermal runaway ZXFBF08 8 Channel Buffer • 14 pin SOIC package ZXFBF25 4 Channel Buffer with output enable OUT4 NC NC IN1 IN4 V+ V- IN2 IN3 NC NC OUT3 OUT2 CONTAINER ZXFBF05N14TA Reel 7” ZXFBF05N14TC Reel 13” INCREMENT 500 2500 RELATED PRODUCTS ZXFBF04 4 Channel Buffer CONNECTION DIAGRAM OUT1 PART NUMBER 14 PIN SOIC PACKAGE ISSUE 1 - FEBRUARY 2001 1 ZXFBF05 ABSOLUTE MAXIMUM RATINGS Voltage on any pin Operating temperature range Storage Temperature 20V (relative to V-) 0 to 70°C (de-rated for -40 to 85°C) -55 to 125°C ELECTRICAL CHARACTERISTICS Test Conditions: Temperature =25°C, V+ = 5.00, V- = -5.00V, RL = 1kΩ, CL = 10pF Parameter Conditions Min. -25 Typical Max.
