Product Summary

The HB244 is an octal buffer/driver designed specifically to improve both the performance and density of 3-state memory-address drivers, clock drivers, and bus-oriented receivers and transmitters. The HB244 is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs.

Parametrics

HB244 absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 V to 7 V; (2)Input voltage range, VI: -0.5 V to 7 V; (3)Output voltage range, VO; -0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI < 0): -20 mA; (5)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (6)Continuous output current, IO (VO = 0 to VCC): ±25 mA; (7)Continuous current through VCC or GND: ±75 mA; (8)Storage temperature range, Tstg: -65℃ to 150℃.

Features

HB244 features: (1)Inputs Are TTL-Voltage Compatible; (2)Latch-Up Performance Exceeds 250 mA Per JESD 17.
