www.ti.com SCBS142U – MAY 1992 – REVISED OCTOBER 2013 3.3-V ABT 16-Bit Buffers/Drivers With 3-State Outputs
Check for Samples: SN54LVTH16244A, SN74LVTH16244A FEATURES DESCRIPTION The 'LVTH16244A devices are 16-bit buffers and line
drivers designed for low-voltage (3.3-V) VCC
operation, but with the capability to provide a TTL
interface to a 5-V system environment. These devices
can be used as four 4-bit buffers, two 8-bit buffers, or
one 16-bit buffer. These devices provide true outputs
and symmetrical active-low output-enable (OE)
inputs. 1 2 Members of the Texas Instruments Widebusв„ў
