Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of 74VHC244; 74VHCT244
Octal buffer/line driver; 3-state
Rev. 01 17 August 2009 Product data sheet
1. General description
The 74VHC244; 74VHCT244 are a high-speed Si-gate CMOS devices.
The 74VHC244; 74VHCT244 have octal non-inverting buffer/line drivers with 3-state
outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A HIGH on
nOE causes the outputs to assume a high-impedance OFF-state.
2. Features
n Balanced propagation delays
n All inputs have a Schmitt-trigger action
n Inputs accepts voltages higher than V
CC
n Input levels:
u The 74VHC244 operates with CMOS input level
u The 74VHCT244 operates with TTL input level
n ESD protection:
u HBM JESD22-A114E exceeds 2000 V
u MM JESD22-A115-A exceeds 200 V
u CDM JESD22-C101C exceeds 1000 V
n Multiple package options
n Specied from - 40 C to +85 C and from - 40 C to +125 C
