The IDT octal buffer/line driver is built using an advanced dual metal
CMOS technology. The FCT541T is similar in function to the FCT244T,
except that the inputs and outputs are on opposite sides of the package. This
pinout arrangement makes these devices especially useful as output ports
for microprocessors and as backplane drivers, allowing ease of layout and
greater board density.
Std., A, and C grades
Low input and output leakage ≤1µA (max.)
CMOS power levels
True TTL input and output compatibility:
– VOH = 3.3V (typ.)
– VOL = 0.3V (typ.)
High Drive outputs (-15mA IOH, 64mA IOL)
Meets or exceeds JEDEC standard 18 specifications
Military product compliant to MIL-STD-883, Class B and DESC
listed (dual marked)
Power off disable outputs permit "live insertion"
Available in the following packages:
– Industrial: SOIC, SSOP, QSOP, TSSOP
– Military: CERDIP, LCC

NOTES:
1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Not more than one output should be tested at one time. Duration of the test should not exceed one second.
4. The test limit for this parameter is ±5µA at TA = –55°C.
