16-Bit Buffers/Line Drivers
SCCS027B - August 1994 - Revised September 2001
Features
Functional Description
• Ioff supports partial-power-down mode operation
• Edge-rate control circuitry for significantly improved
noise characteristics
• Typical output skew < 250 ps
• ESD > 2000V
• TSSOP (19.6-mil pitch) and SSOP (25-mil pitch)
packages
• Industrial temperature range of –40˚C to +85˚C
• VCC = 5V ± 10%
CY74FCT16240T Features:
• 64 mA sink current, 32 mA source current
• Typical VOLP (ground bounce)
<1.0V at VCC = 5V, TA = 25˚C
These 16-bit buffer/line drivers are used in memory driver,
clock driver, or other bus interface applications, where high
speed and low power are required. With flow-through pinout
and small shrink packaging, board layout is simplified. The
three-state controls are designed to allow 4-, 8-, or 16-bit
operation.
This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device
when it is powered down.
The CY74FCT16240T is ideally suited for driving
high-capacitance loads and low-impedance backplanes.
The CY74FCT162240T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for minimal undershoot and reduced ground bounce. The
CY74FCT162240T is ideal for driving transmission lines.
CY74FCT162240T Features:
• Balanced output drivers: 24 mA
• Reduced system switching noise
• Typical VOLP (ground bounce)
<0.6V at VCC = 5V, TA= 25˚C

Notes:
1. H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care. Z = High Impedance.
2. Operation beyond the limits set forth may impair the useful life of the device. Unless noted, these limits are over the operating free-air temperature range.
3. Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground.
4. Typical values are at VCC=5.0V, TA= +25˚C ambient.
5. This parameter is specified but not tested.
6. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting
of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter
tests, IOS tests should be performed last.
7. Tested at +25˚C.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
