EL7156 ® Data Sheet November 3, 2005 FN7280.2 High Performance Pin Driver Features The EL7156 high performance pin driver with 3-state is suited to many ATE and level-shifting applications. The 3.5A peak drive capability makes this part an excellent choice when driving high capacitance loads. • Clocking speeds up to 40MHz The output pin OUT is connected to input pins VH or VL respectively, depending on the status of the IN pin. When the OE pin is active low, the output is placed in the 3-state mode. The isolation of the output FETs from the power supplies enables VH and VL to be set independently, enabling levelshifting to be implemented. Related to the EL7155, the EL7156 adds a lower supply pin VS- and makes VL an isolated and independent input. This feature adds applications flexibility and improves switching response due to the increased enhancement of the output FETs. • 0.5ns TON-TOFF prop delay mismatch This pin driver has improved performance over existing pin drivers. It is specifically designed to operate at voltages down to 0V across the switch elements while maintaining good speed and on-resistance characteristics. Available in the 8 Ld SO and 8 Ld PDIP packages, the EL7156 is specified for operation over the full -40°C to +85°C temperature range.

It contains two analog switches connecting VH and VL to OUT. Depending on the value of the IN pin, one of the two switches will be closed and the other switch open. An output enable (OE) is also supplied which opens both switches simultaneously. Due to the topology of the EL7156, both the VH and VL pins can be connected to any voltage between the VS+ and VSpins, but VH must be greater than VL in order to prevent turning on the body diode at the output stage. where: VS is the total power supply to the EL7156 (from VS+ to GND) VOUT is the swing on the output (VH - VL) CVS is the integral capacitance due to VS+ CINT is the integral load capacitance due to VH IS is the quiescent supply current (3mA max) f is frequency The EL7156 is available in both the 8 Ld SO and the 8 Ld PDIP packages. The relevant package should be chosen depending on the calculated power dissipation. 3-state Operation When the OE pin is low, the output is 3-state (floating.) The output voltage is the parasitic capacitance’s voltage. It can be any voltage between VH and VL, depending on the previous state. At 3-state, the output voltage can be pushed to any voltage between VH and VL. The output voltage can’t be pushed higher than VH or lower than VL since the body diode at the output stage will turn on. Supply Voltage Range and Input Compatibility The EL7156 is designed for operation on supplies from 5V to 15V (4.5V to 16.5V maximum). The table on page 6 shows the specifications for the relationship between the VS+, VS-, VH, VL, and GND pins. All input pins are compatible with both 3V and 5V CMOS signals. With a positive supply (VS+) of 5V, the EL7156 is also compatible with TTL inputs. Power Supply Bypassing When using the EL7156, it is very important to use adequate power supply bypassing. The high switching currents developed by the EL7156 necessitate the use of a bypass capacitor between the supplies (VS+ & VS-) and GND pins. It is recommended that a 2.2µF tantalum capacitor be used in parallel with a 0.1µF low-inductance ceramic MLC capacitor. These should be placed as close to the supply pins as possible. It is also recommended that the VH and VL pins have some level of bypassing, especially if the EL7156 is driving highly capacitive loads. Power Dissipation Calculation When switching at high speeds, or driving heavy loads, the EL7156 drive capability is limited by the rise in die temperature brought about by internal power dissipation. For reliable operation die temperature must be kept below TJMAX (125°C). It is necessary to calculate the power dissipation for a given application prior to selecting the package type. 8 2 TABLE 1. INTEGRAL CAPACITANCE VS+=VH(V) CVS(pF) CINT(pF) 5 80 120 10 85 145 15 90 180 Having obtained the application’s power dissipation, a maximum package thermal coefficient may be determined, to maintain the internal die temperature below TJMAX: T JMAX – T MAX θ JA = ---------------------------------------PD where: TJMAX is the maximum junction temperature (125°C) TMAX is the maximum operating temperature PD is the power dissipation calculated above θJA thermal resistance on junction to ambient θJA is 160°C/W for the SO8 package and 100°C/W for the PDIP8 package when using a standard JEDEC JESD51-3 single-layer test board. If TJMAX is greater than 125°C when calculated using the equation above, then one of the following actions must be taken: Reduce θJA the system by designing more heat-sinking into the PCB (as compared to the standard JEDEC JESD51-3) Use the PDIP8 instead of the SO8 package De-rate the application either by reducing the switching frequency, the capacitive load, or the maximum operating (ambient) temperature (TMAX) FN7280.2 November 3, 2005 EL7156 SO Package Outline Drawing 9 FN7280.2 November 3, 2005 EL7156 PDIP Package Outline Drawing NOTE: The package drawing shown here may not be the latest version.
