8 Detailed Description
8.1 Overview
The SN74AHCT1G00 device performs the Boolean function Y = A × B or Y = A + B in positive logic.
The device has TTL inputs that allow up translation from 3.3 V to 5 V. The inputs are high impedance when
Vcc = 0 V.

8.3 Feature Description
The device is ideal for operating in a 5-V logic system. The low propagation delay allows fast switching and
higher speeds of operation. In addition, the low power consumption makes this device a good choice for portable
and battery power-sensitive applications.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The SN74AHCT1G00 is a low drive CMOS device that can be used for a multitude of bus interface type
applications where output ringing is a concern. The low drive and slow edge rates will minimize overshoot and
undershoot on the outputs. The TTL inputs can except voltages down to 3.3 V and translate up to 5 V.
9.2 Typical Application
Figure 4. Typical Application Schematic
9.2.1 Design Requirements
This device uses CMOS technology and has balanced output drive. Take care to avoid bus contention because it
can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads
so consider routing and load conditions to prevent ringing.
9.2.2 Detailed Design Procedure
• Recommended input conditions:
– Specified high and low levels. See (VIH and VIL) in Recommended Operating Conditions.
– Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.
• Recommended output conditions:
– Load currents should not exceed 25 mA per output and 50 mA total for the part.
– Outputs should not be pulled above VCC.

10 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in the
Recommended Operating Conditions.
Each VCC terminal should have a good bypass capacitor to prevent power disturbance. For devices with a single
supply, TI recommends a 0.1-μF capacitor and if there are multiple VCC terminals then TI recommends a 0.01-μF
or 0.022-μF capacitor for each power terminal. Multiple bypass capacitors can be paralleled to reject different
frequencies of noise. Frequencies of 0.1 μF and 1 μF are commonly used in parallel. The bypass capacitor
should be installed as close as possible to the power terminal for best results.
11 Layout
11.1 Layout Guidelines
When using multiple bit logic devices inputs should not ever float.
In many cases, functions or parts of functions of digital logic devices are unused, for example, when only two
inputs of a triple-input AND gate are used or only three of the four buffer gates are used. Such input pins should
not be left unconnected because the undefined voltages at the outside connections result in undefined
operational states. Specified below are the rules that must be observed under all circumstances. All unused
inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. The logic
level that should be applied to any particular unused input depends on the function of the device. Generally they
will be tied to GND or VCC whichever make more sense or is more convenient. Floating outputs is generally
acceptable, unless the part is a transceiver. If the transceiver has an output enable pin it will disable the outputs
section of the part when asserted. This will not disable the input section of the I.O’s so they also cannot float
when disabled.
