Active 5V bus transceiver for industrial temperature ranges
The SN74AHCT16245DGGR is an active-production 16-bit non-inverting transceiver from Texas Instruments' 74AHCT logic family, designed for bidirectional data flow on 5V buses with 3-state outputs for bus isolation.
Output drive and fan-out limits for bus loading
Each output sources or sinks 8mA (high and low), which is typical for 5V CMOS logic but limits direct drive to a single standard TTL load per line — for heavily loaded backplanes or long traces, a buffer or line driver stage is needed. The two 8-bit elements (Number of Elements: 2) with independent direction controls allow separate bus segments to be isolated or combined under software or hardware direction.
48-TSSOP footprint and board integration
Housed in a 48-TFSOP (6.10mm width) package, also referred to as 48-TSSOP, the part requires a fine-pitch surface-mount layout with controlled impedance traces for the 16 data lines to maintain signal integrity at switching speeds. The 0.50mm pin pitch demands careful solder paste stencil design and X-ray inspection for voiding — standard for this package class.
Compliance and sourcing posture
ROHS3 compliant with no exemptions, the part meets EU and global environmental requirements without restriction.
