3.3V CMOS OCTAL
BUFFER/LINE DRIVER
Integrated Device Technology, Inc.
FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
• ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
• 25 mil Center SSOP and QSOP Packages
• Extended commercial range of -40°C to +85°C
• VCC = 3.3V ±0.3V, Normal Range or
VCC = 2.7V to 3.6V, Extended Range
• CMOS power levels (0.4µW typ. static)
• Rail-to-Rail output swing for increased noise margin
• Military product compliant to MIL-STD-883, Class B
The FCT3244/A octal buffer/line drivers are built using
advanced dual metal CMOS technology. These high-speed,
low-power buffers are designed to be used as memory data
and address drivers, clock drivers, and bus-oriented transmitter/receivers. The three-state controls are designed to operate these devices in a dual-nibble or single-byte mode. All
inputs are designed with hysteresis for improved noise margin.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 3.3V, +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. This parameter is guaranteed but not tested.
5. VOH = VCC –0.6V at rated current.

2. Typical values are at VCC = 3.3V, +25°C ambient.
3. Per TTL driven input; all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fCPNCP/2 + fiNi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆ICC = Power Supply Current for a TTL High Input

2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays
and Enable/Disable times should be degraded by 20%.
