Philips Semiconductors Product specification
74F3037Quad 2-input NAND 30Ω driver
FEATURES• 30Ω line driver
• 67mA output drive capability in the high state
• High speed
• Facilitates incident wave switching
• 3nh lead inductance each on VCC and GND when both
side pins are used
• 160mA output drive capability in the low state
• Industrial temperature range available (–40°C to +85°C)
DESCRIPTIONThe 74F3037 is a high current line driver composed of four
2–input NAND gates. It has been designed to deal with the
transmission line effects of PC boards which appear when
fast edge rates are used.
The drive capability of the 74F3037 is 67mA source and
160mA sink with a VCC as low as 4.5V. This guarantees
incident wave switching with VOH not less than 2.0V and VOL
not more than 0.8mA while driving impedances as low as 30
ohms. This is applicable with any combination of outputs
using continuous duty. The propagation delay of the part is
minimally affected by reflections when terminated only by
the TTL inputs of other devices. Performances may be
improved by full or partial line termination.

DC ELECTRICAL CHARACTERISTICS(Over recommended operating free-air temperature range unless otherwise noted.)
Notes to DC electrical characteristics For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. All typical values are at VCC = 5V, Tamb = 25°C. IOH1 is the current necessary to guarantee the low to high transition in a 30 ohm transmission line on the incident wave. IOL1 is the current necessary to guarantee the high to low transition in a 30 ohm transmission line on the incident wave. IO is tested under conditions that produce current approximately one half of the true short–circuit current (IOS).
