Product details
Overview
74LVCH16244AEV,151 from Nexperia is a 16-bit 3-state buffer/line driver with 5 V tolerant inputs and outputs, bus hold on all data inputs, IOFF partial power-down support, and Schmitt-trigger inputs for noise immunity. It operates from 1.2 V to 3.6 V supply and is rated for -40 °C to +125 °C ambient temperature. It serves as a level-translating interface between mixed-voltage subsystems in industrial control backplanes.
For engineers reviewing the 74LVCH16244AEV,151 datasheet, 74LVCH16244AEV,151 pinout, 74LVCH16244AEV,151 application, or 74LVCH16244AEV,151 equivalent, key selection criteria include 5 V tolerance with 1.2 V–3.6 V core supply, bus hold elimination of external pull-ups, IOFF protection during power sequencing, propagation delay ≤4.1 ns at 3.3 V, and TSSOP48 package compatibility with high-density PCB layouts.
Technical Context
The 74LVCH16244AEV,151 implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Its bus hold circuit sustains logic states on unused data inputs without external resistors, drawing ±75 μA at 3.0 V with VI = 0.8 V or 2.0 V.
IOFF functionality disables outputs when VCC = 0 V, blocking backflow current during partial power-down. Schmitt-trigger inputs tolerate slow rise/fall times (Δt/ΔV up to 20 ns/V at 1.2 V), and the device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its voltage ranges.
Key Specifications

FAQ
What is the maximum supply voltage for 74LVCH16244AEV,151?
The absolute maximum supply voltage for 74LVCH16244AEV,151 is +6.5 V, but recommended operation is limited to 1.2 V to 3.6 V. Exceeding 3.6 V risks violating functional specifications and may cause premature wear. The 5 V input/output tolerance applies only to signal pins-not VCC-so maintaining VCC within 3.6 V ensures correct internal logic levels and bus hold behavior in 74LVCH16244AEV,151.
Does 74LVCH16244AEV,151 support true bidirectional data flow?
No, 74LVCH16244AEV,151 is a unidirectional non-inverting buffer with fixed input (A) and output (Y) terminals. Each of the 16 channels flows strictly from A to Y. Directional control is not supported; for bidirectional translation, separate transmit/receive buffers or dedicated transceivers such as 74LVC245 must be used alongside 74LVCH16244AEV,151.
How does the bus hold feature behave when an input exceeds VCC?
Per the datasheet, the bus hold circuit in 74LVCH16244AEV,151 is automatically disabled when VI > VCC, allowing safe application of 5.5 V signals even with VCC = 1.2 V. This ensures compatibility with 5 V inputs without contention or excessive current draw. Bus hold remains active only for inputs within 0 V to VCC, preserving state retention where needed in 74LVCH16244AEV,151.
Can 74LVCH16244AEV,151 drive standard TTL loads?
Yes, 74LVCH16244AEV,151 directly interfaces with TTL logic: VOH ≥ 2.2 V and VOL ≤ 0.55 V at VCC = 3.0 V and IO = ±24 mA meet TTL input thresholds. Its 5 V tolerant outputs swing rail-to-rail relative to their driven bus, and Schmitt-trigger inputs accept TTL-compatible edge rates. This makes 74LVCH16244AEV,151 suitable for upgrading legacy TTL subsystems without redesign.
Is the 74LVCH16244AEV,151 pin-compatible with older 74LVCH16244A variants?
Yes, 74LVCH16244AEV,151 uses the SOT362-1 (TSSOP48) package and shares identical pinout, electrical characteristics, and functional behavior with other 74LVCH16244A variants in the same package-including 74LVCH16244ADGG. The "EV" suffix denotes the specific tape-and-reel packaging variant per Nexperia's ordering convention, not a functional revision; thus 74LVCH16244AEV,151 drops into existing footprints without layout change.
