74AHC2G241; 74AHCT2G241
Dual buffer/line driver; 3-state
Rev. 01 — 10 March 2004
Product data sheet
1. General description
The 74AHC2G241; 74AHCT2G241 is a high-speed Si-gate CMOS device.
The 74AHC2G241; 74AHCT2G241 is a dual non-inverting buffer/line driver with 3-state
outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A
HIGH level at pin 1OE causes output 1Y to assume a high-impedance OFF-state. A LOW
level at pin 2OE causes output 2Y to assume a high-impedance OFF-state.
Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise
and fall times.
2. Features
■ Symmetrical output impedance
■ High noise immunity
■ ESD protection:
◆ HBM EIA/JESD22-A114-A exceeds 2000 V
◆ MM EIA/JESD22-A115-A exceeds 200 V
◆ CDM EIA/JESD22-C101 exceeds 1000 V.
■ Low power dissipation
■ Balanced propagation delays
■ SOT505-2 and SOT765-1 package
■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C.

capacitance
CL = 50 pF; f = 1 MHz
[1] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + ∑(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
∑(CL × VCC2 × fo) = sum of outputs.
[2] The condition is VI = GND to VCC

For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
17. Definitions
18. Disclaimers
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Life support — These products are not designed for use in life support
appliances, devices, or systems where malfunction of these products can
reasonably be expected to result in personal injury. Philips Semiconductors
customers using or selling these products for use in such applications do so
at their own risk and agree to fully indemnify Philips Semiconductors for any
damages resulting from such application.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
