This datasheet provides the features and characteristics of IDT54/74FCT16244T/AT/CT/ET, IDT54/74FCT162244T/AT/CT/ET, IDT54/74FCT166244T/AT/CT, IDT54/74FCT162H244T/AT/CT/ET, including interfaces, power consumption, temperature range, etc.
The IDT54/74FCT16244T/AT/CT/ET family provides high‑speed, low‑power 16‑bit buffer/line driver functions for bus interfaces and signal buffering. Variants offer high‑drive, balanced, light‑drive and bus‑hold options, with output currents ranging from ±8 mA to ±64 mA and built‑in ESD protection.
The datasheet specifies pin assignments for SSOP, TSSOP, TVSOP and Cerpack packages, absolute maximum ratings, electrical characteristics such as input/output capacitance, logic thresholds, output voltage levels, and detailed switching parameters. Temperature ranges cover commercial (‑40 °C to +85 °C) and military (‑55 °C to +125 °C) environments.
| Output HIGH Voltage (VOH) | VCC = Min., VIN = VIH or VIL |
|---|---|
| Output LOW Voltage (VOL) | VCC = Min., VIN = VIH or VIL |
| Storage Temperature (TSTG) | -65 °C to +150 °C |
| DC Output Current (IOUT) | -60 mA to +120 mA |
The FCT16244T version provides high‑drive outputs of –32 mA I_OH and 64 mA I_OL.
Yes, the FCT162H244T variant includes bus‑hold that retains the last active bus state during three‑state operation.
The device is available in 25 mil pitch SSOP, 19.6 mil pitch TSSOP, 15.7 mil pitch TVSOP, and 25 mil pitch Cerpack packages.
